Just wondering when you get a limp mode

is the ecu still good ?

PROcede runs really strong when it's running like it's suppose to

But, for some reason my PROcede is acting up ?

Please help me out, it works awesome until now...

My other alternative is AA + the AA exhaust, 420 crank hp to bolt ons. And it's only $2,600.00

You need to post specific information about your car if you want help.

Transmission?
Octane fuel?
Last time you refueled?
PROcede firmware version?
PROcede map version?
How many miles/redline pulls since you changed maps/firmware?
What RPM did the limp occur at?
Did the limp occur just before or after a shift?
Ambient temp when the limp occured?

That's the bare minimum.

?? acting up like under what circumstances do you induce these limps??

If it's been running fine as he said, fuel would be suspect. If it was me, I would use the PROcede reader software to reset the ECU, then disconnect the battery for an hour or more, and start learning from scratch.

More often than not, unexplained and sudden stuff like this is caused by bad fuel. If it was something serious like a splice coming loose, he'd be throwing codes all over the place...

Got it, ya. I'm gonna get the 2.1 upload when I fix the limp code and get new fuel lines...

1) Make sure you have the most up to date Procede Firmware and Map ( make sure you pick the correct transmission)

Go here: http://www.vishnutuningforum.com/for...=2375#post2375

and

Download the v2.0 PROcede User Software from: http://www.vishnutuning.com/Files/BM...eader_v2_0.zip

2) Update your Procede, then disconnect your battery for 1hr to reset the ECU.

3) Not sure if you had the V1 before the V2, if so, make sure your boost lines are connected back nice a tight, no leaks.

4) Get some Sunoco Ultra 93 or 91

5) Test by taking some hard pulls from 1-4 to achieve max boost pressure to see if you go limp.

If you go limp try this (assuming it you go limp at the high RPMs, you never told us)

If this happens, the ECU will keep the throttle from going wide open until the pressure is discharged. If you have a PROcede, you can simply use the User Tq table to drop UT to something low like 60%. This will solve that problem without making your car any slower since the throttle starts to close itself around 6800rpm.

Basically dial down UT settings at 6500 RPM and higher from the 90 default to something lower like 75, 70, 65 etc. until the limp goes away. There was another post on this I could only find the 2 below.
