Hi. First of all i want to say thanks! to all who makes this site awsome. Im new to Corvette and will get mine shipped in a week... Although i still need to look the car over and get a 100% overview of its condition, its supposed to be a 70.000km 97mod auto. Now i know the km have been adjusted when shipped to philippines from Japan, but i have no proof its only 70k... Anywho its all stock, black and have magnesium wheels. Fully loaded version as i understand.

Being stock it also means quiet...Dont like that so my first question is what intake and exhaust is recomended for a bigger "grunt" for the money. I know it wount give me moore power but i wold like the sound to seem like its faster :-)

Next question is ECU related. What type ECU is in the C5 97mod? Is it a flexible ECU that easely can be programmed ore is it all set in stone? I have seen these "chipping" tools you connect...is this available for this model and with exhaust and intake and tune, what can u expect of changes in power?

My last question is what wold be the best "bang for the buck" route to go to get more power when that time comes? Since its auto i think im not going to do any crazy supercharger setup ore turbo conversion. Only make it a bit moore "fresh" for now...

Im familiar with european cars, and have been a BMW fan for my whole life. Also american muchels iv had a few of (Lightning SVT, Mustang HT 68mod, 400SS Silverado and so on) But i am new to the Corvette world so i hope to learn from thise walking the path before me :-)

Again Thanks

RCS

Welcome to the Forum.
Don't mind him. He is the resident cranky on this Forum. Am sure you will get more helpful answers very soon.

RCS

Well i get his point, but there are always new products out there so... :-)

My questions seem to be a bit to newb so im searching alot to find others opinion in old posts. Thanks

3boystoys

Last c5 was 2004, 11 yrs, not a lot new for the C5 these days.

RCS

Well from experiance from old european cars and also ricers there are always new product made. Not from the manufacturer but from the aftermarked. But im new to Corvette so maby that market is stagnant...what do i know 😆

3boystoys

I'm sure there will be issues to tend to before any mods, Get it home and see how it runs/drives 1st.

RCS

Thanks daddy for the advice 😆

Just kidding. But u shuld know im not new to cars. Been selling and working on cars since i was 13. This specific Corvett C5 mod is new to me but how a car work is not ☺.

Enough about that. I only bought it to sell it again. But b4 i will sell it i will enjoy it ☺. Tuning is something 90% want to do with these cars if only to get moore sound and feeling of a fast car. Many here can give me the info i need to make the choices fit for me... Your advice is moore the advice i wold give my son 😊

3boystoys

So, how much $$ do you dump into a 17yr old car just to sell it? Get it running good and move on if your plan was just to sell it anyway, why add mods that you'll never get your money back from?

RCS

So your not realy into sales? Its werry comman that carcompanys do things to cars to make them attractive to the buyers. In US the buyers are diffrent then here. Here only few can afford sutch a car. They want it to sound like a propper muchelcar... and look good. Here Chrome wheels are eyecandy the ritch cant resist ☺.

To be honest this is 50/50 for me and for the buyer. Im expecting it to take time. Since i got it for a verry good price there is room for some mods that will make me and a potential buyer happy. I do not belive there are many buyers here that want it stoch. They want to show off moore then anything.

Hope it answered your question

c4_4ya

So what about advertising it as-is and also include pricing options to potential buyers on certain exhaust, performance, wheels, tint, etc? That way they can have it customized to their liking and you have them pay for the upgrades that they want.

RCS

Well that culd work... especialy at home and US. But it takes to mutch time getting parts here the "right way" so im afraid customers, the few that actualy can afford it, wold like it clean with the V8 sound and some blingy wheels....

But one important thing to mention. I bought it for half price of what they usualy ask here. I have never had a Corvette so i want to keep it for a while and see how i like it. Can i hear that beutifull V8 sound a coupple of times im a happy camper. If i spend 800$ on exhaust im still making money ans had fun and satisfaction at the same time. The buying selling thing is moore for fun then the money... but its always nice to make a little whenever there is a chance :-)

At whorst noone wants it and ill keep it. Fine by me :-)

SOME FACTS FOR YOU!

You don't CHIP a C5/C6 PCM. You have to have a tuning standalone software/hardware set up like EFI Live or HP Tuners to interface and FLASH the PCM to the new parameters. The learning curve to do the tuning properly is VERY STEEP!!! Anything other than a PCM flash is rip off crap!

Its expensive to have a shop tune it $450-$500 UDS

Where do you live???

You can purchase a hand held tuning device but,,,, Tuning IS NOT going to do anything for sound.

The only way to change the sound is :

1- Axel back exhaust system.
2- Cam
3- Increased Compression, with the cam.
4- Headers

For just SOUND,, the AXEL BACK system is the key.

For power with an auto, you would need to do a differential gear swap to wake the car up. That cost a LOT and requires a new differential housing for anything bigger than a 315 ratio.

You better PRAY that there isn't anything wrong with the EBTCM, Steering Wheel Position Sensor or Instrument Cluster.

You CAN NOT get new a EBTCM, Steering Wheel Position Sensor parts.


Instrument clusters are hard to get over seas and even more difficult to program in the correct mileage .

Good luck my friend,

Here a present for you...

READING YOUR Engine Diagnostic Codes



The Diagnostic Display Mode is entered with the following procedure:

1) Turn on the ignition but don't start the engine. NOTE! You can read the DTCs with the engine running and or driving down the road but it can distract you. BE careful! Some DTCs clear themselves when you turn the ignition OFF!

2) Press the RESET button to turn off any warning messages. (i.e. door open, trunk open ect)
3) Press and hold OPTIONS
4) While holding OPTIONS, press FUEL four times within a 10-second period.


Initially, on-board diagnostics go into an Automatic Mode which shows diagnostic codes in a pre-set sequence: PCM - TCS - RTD - BCM - IPC - RADIO - HVAC - LDCM - RDCM - SCM - RFA. All codes will be displayed for each. ( i.e. PCM = 4 codes) If none are present in a given module, you will see No More Codes on the display.
There are two kinds of diagnostic codes, Current and History designated with a letter suffix, “C” or “H”. A current C code indicates a malfunction is present and active in the module displaying data. A history code indicates a problem existed sometime in the last 40 or 50 ignition cycles. When not accompanied by a current code of the same number, it's potential evidence of a previous problem, now resolved, that was not removed by clearing the codes.
More likely it's an indication of an intermittent malfunction.
Intermittent codes are the most challenging of the diagnostics. An intermittent code may have happened once, may have happened more than once but is inconsistent or may be happening on a regular basis but not at the time the codes are displayed. History codes can also be caused by a current malfunction in a system that is not operating at the time codes are displayed. An example is the rear window defogger which doesn't operate until the Body Control Module detects engine rpm. For history codes set by a module that does not operate with the key on and engine off, a special diagnostic tool called a Scan Tester is necessary to properly diagnose the malfunction.
Once the system has displayed all modules, it goes into the manual mode which allows selection of each module using combinations of Driver Information Center buttons. Manual mode can also be entered during the automatic sequence by pressing any button except English/Metric (E/M). Once the display shows Manual Diagnostics, select a module by pressing the OPTIONS button to go forward or the TRIP button to go back. Once a module is selected, a code is displayed, and if more than one are present; press GAGES to go forward or FUEL to go back.
To exit the diagnostic mode at any time, press E/M. If you want to erase codes in a given module, press and hold the RESET button To reset the codes once in manual mode, press and hold RESET until it displays NO CODES Press OPTIONS to go to the next module. Repeat the steps until you have reset the codes in all the computer modules.
NOTE!! Only reset the codes IF you want to - it is NOT necessary to do this. Clearing a code does not repair a problem. You are simply erasing the evidence of it in the module's memory. If you clear the code/s, and extinguish the Check Engine Light, your emissions status ready will NOT allow you to pass an emissions test until you have completed the required driving cycles.
Once you have the codes, the next question is: What to do with the information?
First, consult the factory service manual. Any serious C5 Do-It-Yourself owner should invest in the Corvette Service Manual of the appropriate model year. The Service Manual is really a requirement if you want to understand and work on your C5. You can GOOGLE the DTC and also find information on it.




Here are some very good sites that explains the DTCs:

Apresiate your answer. Remember im Norwegian so some tecnical words i might not remember as i write. Of corse you dont "Chip" in the sense we did with the old Silvia ore other cars. But the idea is still the same. Out with old software and in witch new. Some ECU`s are werry flexible to tune and make adjustments from others not so. The handheld units i have read alot about but there are many and im shure also diffrent tunes depending on what you do and what parts you use. Changing cams wold probably mean even more extensive programming...? And of corse it wount do anything for sound...

EBTCM.... Thats new valuable info for me... How wold you know if this is broke? Im shure you wold feel it on the handeling in some way... Is this a comman problem and what do most do if this happen? I have read alot about codes and also about comman issues, never incounter this one yet. But the steering colom lock i have understood is an issue. So im ordering parts for this issue as we speak...

I live in Philippines and here we have no Corvette specialists ore parts. All will be ordered trugh internet. So its better to have some crucial parts ready right away.

When i get the car here ill do moore extensive checkups of the car. I have learned alot from this forum already and to be honest i love it! his is half the fun to get to know the car inside outside. Thats the way its been with older BMW for me... Now im giving Corvette a chance.

Btw im sorry if i come off as "mr know it all". I certainly DONT know it all, but at the same time i hate being treated as a kid getting his Corvette from his ritch dad. I have been around cars since i was 13 and had many fast cars running on diffrent types of fuels and tunes. So im not total newb. But im trying to be humble and learn from those that knows moore...

Again thanks for the info. Cant wait to get the car here and hope there will be no major problems. If ever that happen i hope its fixable even though im here in 3rd world contry.

Yes, changing the cam would require tuning. The guys that tune these cars properly have years and years of experience. It's not something you can learn overnight.

A cam WILL change the sound of the car. Maybe not make it louder per se but it will change the sound.

C5's are electrically temperamental cars. Make sure you have a fully charged battery before you go tearing into problems that might not even exist.

About the tuning part of corse i culdent do it myself. I have a fair understanding of ignition times and those things but nothing beats experiance. But these handheld tuners do tune your car to specific parts being used? Meaning you can get a tune for them that already have the setings of your cam, exhaust and so on? If you start with turbo(s) ore kompressor im shure you need a new fully adjustable ECU. THe ECU in Corvette is not that flexible?

Yes i have been reading about the ground problems and also issues due to bad battery. Makes it a challange owning a corvette, but if you like tinkering, like i do, its ok. But noone like the realy big bills...And for me living in the Philippines its not so easy to get qualified mechanics to help.... Things are just done so diffrently here.

You asked "How do I know if there is a problem with the EBTCM?"

Just like ANY problem with a system in your car, you will see messages in the DIC and it will also set a Diagnostic Trouble Code (DTC).

If there is an issue with your car,, you will most likely see a DTC that will point you in the correct direction. You need to learn how to retrieve, read, understand and use the DTCs to point you in the right direction for troubleshooting and repair.

Yes,,, There will be times when you will have an issue and not see a DTC but, that is a symptom in its self.

ELECTRICAL ISSUES, Just as ggroller stated,, C5s are VERY sensitive to battery voltage. If your battery cant provide the correct voltage and current, it will cause a whole host of strange and crazy problems.

Im exited to learn! Thanks for all the good info on this car. This shows the worth of a forum like this. It wold take long time to figure out all of this by myself, if ever. Im glad there are experianced enthusiasts that share with us other newbs

Btw i just did some fixing on the road to the house...Did i mention i live in Philippines? I realy hope i can get it to my house

You got it cheap but you have to ship it by Cargo Ship I assume, then your going to drop a bunch of $$ into it in a market that's hard to sell cars like this. Maybe you really need to rethink your approach, you don't actually buy/sell cars for a living do you?

Make sure you start your diagnostic process by these first two steps, If not you can just be spinning your wheels (wasting your time and money)

(1) As mentioned earlier, New quality battery (Optima)

(2) 'INSPECT' and 'CLEAN, ALL' your Ground connections on a C5. There are numerous locations for grounds on chassis (6-8) I believe, check forum Tech for exact number. A lot of electrical issues stem from this one issue alone.
Research and Good Luck, that's what's nice about this forum, you get real life answers and sometimes a polk in the eye for humor!!
