I'm a newbee & kinda lame on the tech side :o .

1. Can you briefly explain a "Mail Order Tune".
2. What I need to do when I get the part.
3. What HP are you getting on Dyno tunes?
4. An estimate of what I could expect from a Remote Control - Mial Order Tune?

Thanks

 

Can you install headers, exhaust, intake and tune? Package deal?

 

Hey Jim. You remove the computer and send it to them. They modify the program and send it back.

 

Hey Jim. You remove the computer (ecm /pcm - whatever the correct lingo is for C6) and send it to them. They modify the program and send it back. Some people (with a lot of money) will buy an extra computer and send it to them so that they can keep the original stock program and have no down time.

 

We are a Corvette specialty shop and pretty much do everything from bolt-ons, dyno tuning , stroker motors,
super chargers ect ect. We are an authorized Callaway
Distributor. Gains of 15 to 20 Rear wheel Horsepower and
Torque across the rpm band are typical tuning an LS2! We are also WD
for TPIS and do research and development for them
Thanks

 

Ls2 Gains we have accomplished on our Dyno

1. Cut out air lids with Amzoil stage II filters 8HP 10 Ft Lbs.
w MAF descreen
- Added Corsa exhaust and got 15 HP & 12 Ft lbs total- No tune

2. TPIS Full Length Headers with high flow cats 20HP & 20 FtLb
- added Magnaflow Mufflers 34HP & 30 Ft Ft Lbs - No tune

3. Callaway Honker Only 16HP 14 Ft lbs
- w Maf descreen
4. Just Tune - Nothing else 16HP and 20 ft lbs
These were all various C6's we had at the shop, some were before LS2 edit was available and will be back shortly for
tuning! All runs are kept as close as possible to 200 F coolant
and 200 Oil temp on dynojet 248 with the latest software!
What was amazing is that these C6's stock were all most identical graphs when stock 348Hp 349 TQ! The numbers
at the top are all rear wheel!

 

Excellent Ron. That is just the kind of data we are looking for - with incremental gains quantified And those numbers are believable as well. I am surprised at the increase with the just adding the Magnaflows after installing headers. What p/n were those magnaflows? I assume they removed the OEM exhaust, spliced in the mufflers and kept the stock tips ?


p.s. we definitely would like an update after you do LS2 edit on those that are coming back.

 

i was wondering how you tune using the LS2 EDIT when the full version isnt out yet? Without access to all the parameters im guessing you couldnt tune to its full potential?

For instance, i had a cam installed in my C6 the other day. The cam alone got me 52 RWHP on the STOCK programming. After numerous attempts to try and tune with the limited access to the parameters we werent able to gain any power AT ALL. There was a full 2 point A/F ratio difference(stock being 11.3 or so and the LS2 edit one being 13.1 - 13.3) also there was timing being added and then on other runs timing being taken away. Again all runs were within 1 HP of each other. Supposedly there are a few "key" parameters that my tuner cannot access to get the full potential. He also said the beta version (the one that is out now) is only a small portion of things that you're able to adjust compared to LS1 EDIT (full version).

 

Great power from the cam. Can you share the specs on the grind.

Thanks

 

230/236 .590/.598 112 LSA + dual valve springs,titanium retainers,hardend push rods,valve seats,valve stem seals

final numbers were 405 RWHP (SAE)

 

Thanks for the quick responce. How is your idle, are you getting much chop?

I was looking at 224/230 581/588 114 lsa.

Not quite as agressive.

I have Kooks, magnaflows, low temp thermostat and tuning. I'm at 390 rwhp befors cam.

How does the car feel at 405 rwhp+

thanks

 

We have the latest version-- Just released-- Make sure your
tuner makes the timing changes in both low and high octane
tables the computer jumps to the low table for management
torque management! Are you saying that 2 full points of air-fuel
ratio change did not change the HP or Tq anywhere in the rpm
ranges?? you can highlight the high octane table and copy and
then highlight the low and paste -- now they are the same the
computer can jump to the low and its the same-- you have to do it this way because there is no way to stop the computer from jumping
to the low octane for tq management ! Hope this helps

 

Gawd I love the computer age. Just think, once we get solenoid actuated valves, we can "copy and paste" a new cam into our engine in 5 minutes.

 

idle sounds great!! to me anyways...some people probably wouldnt like it just because its not smooth anymore, ya know. There is NO problem telling that there is a bigger cam in there now (at idle)

as far as power there is a noticable power gain, up top especially...down low doesnt feel too bad either. The biggest thing is now that the cam is in the weather is horrible right now...high temps (90deg.) and very high humidity. As soon as it cools down outside i will be better able to compare

 

thanks for the response..

when you say the latest version does this mean its still the "beta" version or the full all-out access to all parameters. I'm having Steve from Dynotec motorsports tune the car. According to him when he spoke to Ken (maker of LS1 & LS2 EDIT) he said more parameters will be accessible in the newer version in about 2 weeks, thats why im trying to figure out what version you guys have....maybe we have an older one...???
ill have to check out the low and high octane tables and see where they are set. I know when comparing the stock tune (absolutely NOTHING changed) and the last tune we tried (which had A/F ratio set at 13.1 to 1 and some extra timing) there was no gain whatsoever. The dyno runs were about 2 mins apart, just long enough to re-flash. Also, the car was experiencing spark knock as shown on the TECH 2 scanner and the dyno graph (i also noticed this same exact "dip" in the graph the Lou from LG motorsports posted...Longtubes,cam,heads,etc.) it looks like that car was doing the same thing at the same time, he also was using the beta version as far as i know. But when the stock program was used there was no spark knock and no "dip" in the graph. Steve was saying that there should be some type of Torque limiting factor that he cant access like he can when using LS1 EDIT. Not to be confused with shutting off the torque mgmt that happens in between shifts. Lastly, the idle recovery is horrible (when coming to a stoplight and clutch is pushed in) im pretty sure he adjusted the recovery rate or whatever its called but maybe it needs more. Its not as simple as drilling a hole on the throttle blade like on the LS1's because the C6's have drive-by-wire and no IAC. The tuning is so new on these and so far kinda difficult IMO. Any comments or ideas?

also, now that i think of it im pretty sure the low octane settings were left unchanged for safety reasons but i will have them changed to match the other ones. Thanks for the help

 

Another tip on the ls2 edit-- make sure you have the target air fuel
for Catalyst overtemp at the same as your PE tables. The Ls2
will go to overtemp mode (fat rich) with just a bolt ons!

 

Nope, no such thing...just ask all the experts on this forum, they'll tell ya all about it.

 

Yeah, I am wondering why the TM-skeptics are not weighing in on this thread.
