Thats funny. I like that line.

 

I have EFI Live, LC1 wideband, and a 1997 C5 with a 228/232 cam, LG Street's, ported 243's, and 42# injectors. I'm VERY confident that my tune will get you up and running enough to drive around.....probably in less than 30 minutes (to swap table information).

Send me a PM with your email address and I'll get you my latest tune.

 

If you do all of your tuning with the stock injectors and then replace them with the 42lb injectors, won't you have to redo all of your VE tables after scaling the injector IFR table? If so, why not go ahead and get the injectors in now so you only have to go through that process once?

 

That's a great offer, take ihim up on it...open it up as an alt tune with your current one, and then use the compare feature to note all the differences between the two tunes.

From there, you will get a much better idea of everything that needs changing, and (hopefully) why. Once you become beter familiar with it all, you can fine tune it from there...but this offer should work pretty well for you if you just use it as-is.

 

NOOOOOOOOOOOOO! VE tables should be independent of injector flow rate! Too many people try to scale VE tables to compensate for injectors....that's the FORD way of doing it (Fords need a MAF change or VE change for older models since there wasn't an injector variable).

With a solid VE tune, you can just rescale the injector table for the 42's....I wouldn't recommend going back to the 28's. Start with a 42# tune and go from there.

I just posted a message that I have a VERY similar cam and engine setup (not the same TB and intake however) but my tune should get him up and running with the 42's....and I have EFI live so he can open and compare both tunes side by side.

 

I believe they are being held in Richmmond at the Richmond Speedway this Sat. Gates open at 10AM.

 

You should have him send his tune to you, and you swap the tables for him. You can set the whole tune up for him, save it and send it back. You dont have to license it with EFIlive. Only he has to license it to flash it. Because you are more experienced, you'll have a better chance of picking up on something that may not look right.
JMHO.
Again, if you need any help just holla LOL.

 

You are correct. Hopefully we will be there with one of our beasts.

 

This is a great thread. I am just getting into tuning my 01 A4 using HP Tuners and am all ears!

 

I'm not a tuning expert by any stretch, but I wasn't sure if VE would change if the IFR scaling went up or down.

I saw that you offered up your tune. Kudos there! It seems that your specs are very close to his and should get him going in no time.

 

Once the VE is dialed in, if you change injectors, all you have to do is scale the IFR until you trims are back to what they were with the other injectors.
I've plugged in injector tables after injector swaps into cars I've previously tuned, and then had to skew those tables by a few % to get the trims perfect.

 

Good info to know. I wasn't sure if the numbers in the VE table were strictly for the PCM to determine the amount of air going through the engine at a given load/rpm or if there was some element of fueling that went along with them.

 

Yes, good point...but then again couldn't you just slightly skew your IFR to compensate for LTFT's slightly rather than skewing your entire VE table and multiple others (MAF, etc)?

Good suggestion ecdmat.... dmiz0420, just email me your tune to billj (at) speedfreaks-ct.com and I'll compare it and get you a revised tune. In the meantime you can be installing your 42# injectors. You'll have to owe me a beer or something when its all running...

 

Short answer, yes. The biggest thing is getting the VE right, regardless of the IFR. The VE with a bigger cam will be decreased down low, and increased up high. Thats what a performance cam does. It decreases VE down low, and increases it up high.
So, once the table is set, if you change injectors, the VE of the engine doesnt change, just the reference the computer uses for the equation. So, if you put in 42s, and plug in a typical 42 table, and you have FTs in the say, 5% and you had 2-3% before, just skewinig the IFR table by 2% will put you right back where you were.
Same goes for the MAF. You adjust it using A/F correction, either with a WB or STFT. Do that for the lower portion, and then skew the upper end by % until you get the A/F ratio where your PE is set for.
What you end up with is a tune that is +or- 2-3% with the MAF on or off. And the WOT fueling is very, very consistent.
You can always tell how good a tune is by turning off the MAF. If it runs the same in SD as it does with the MAF, that is a good, complete tune. Same with open loop or closed loop. If it runs basically the same, its dialed in really close.
OK, enough secrets. Please send all checks to me @ edmat-l1@msn.com. LOL/JK

 

I feel your pain!......No, Wait!.......I understand your pain!

I just finished installing the LC-1, added it to the table display and built the afr gauge on my HPT and it only took me two weeks to get this done! Oh Brother! This tuning stuff does have a huge learning curve!

My car has been tuned (not very well) and running for a year or so now so I'm not in a huge hurry.

If I was anxious to get a car running, now wouldn't be the time to learn how to tune. Let someone get it going for you and keep the tuning software to play with it later when you have the time to enjoy learning how to tune.

 

the best is coming to you! let him set it and then forget it

 

Worse than all the airplane ground schools all put together, that I ever went through in 40 years of flying.
We all went through it. The more you work at it, the easier it gets. There is alot of help out there. I have EFI Live and their help forum is good: http://forum.efilive.com/

also LS1Tech.com.

I hope you have a printer, I printed out all the manuals and everything off the forums.
Be sure to look at the Tutorials on EFILive:

I know you have a 97 and you have the early computer which has some limitations.
You didn't mention sun light blanking out the laptop screen or loging and looking for the Pooolice!

Take the member with the 97 with mods like yours offer on using his tune. It will help you learn by comparing the two.

Cheers, Curt

 

Unfortunately, I have to go out of town next week. If you'd like to wait, I'm in Centreville and have some experience tuning. I'd be willing to help you get started. Shoot me a pm.

 

Bill dog, I'll buy you a keg. Ever go to VIR? I'm sending my bin file over now.... sorry I dodn't get back sooner, I've been over on the EFI live forum getting lead around by the nose.

I found out apparently there are bad 6 wire Innovate LC-1 units?!?!?!? Innovate hasn't listed serial #'s affected, you have to call them to find out. Nothing like being straight fwd with a great product (dripping with scarcasm)

To innovate's credit at least they have relivent instructions with relivent # of wires and wire colors. THis is in contrast to the EFI instructions which contradict themselves and the innovate.

I wanted to actually talk to Doug before he left. I can't get my car down to richmond. It doesn't drive. I was hoping to meet him in Tysons. on his way down 95 (495) there. I do appreciat his offer to help though. If I could get my car to richmond I wouldn't go to bed and wake up for the last 3 weeks. It's hard to believe we pay money for the companies to take advantage of us like this.

Why should this be any more difficult than installing a stereo? THe tuning part I understand, but just the wireing is a managery.

Evil grips of tuning..... I got plenty more where that came from......

It's all I can do to put this out there and hope these companies correct their minor but critical errors and discrepancies in their instructions.

If I struggled through it silently, I wouldn't be helping out the community that has helped me so much and still continues to. I really do appreciate all the time and help you guys are putting into this and I'm super stoked others are finding it useful. I think If I had out a title like help with wiring it would get the 0 responses that it has gotten from when I posted it yesterday. Wait, I got a response telling me I was in the wrong forum, but I posted it in scan and tune and tech.... I do have some gray matter.... though this process is torching it.....

 

I'm all over this offer......
