Hey anyone knows of a way to remove the rev limiter on the 5AT's, I heard that you can remove the ABS fuse, this will improve it from 2000 to 2500.

Any other ways to do this??

Would appreciate the info

 

Not quite sure what you're asking, but I'll make a guess. The rev limiter is set at 6600rpm (at least on my '04 coupe) and protects the engine from damage if you rev it too high. The limit can only be changed by reflashing the ECU.

I'm guessing you're talking about the stall speed of the torque converter, which is the peak engine RPM with the transmission in gear and the vehicle being held at a stop (about 2400rpm or so). Since the torque converter is a mechanical device that connects the engine to the transmission, the stall speed can't be changed without installing a different torque converter.

Pulling the VDC fuse in the engine compartment turns off the VDC and ABS, allowing you to spin the wheels freely in a burnout if you wish, but does nothing to affect the rev limiter or torque converter.

 

Technosquare can re-program your ecu for roughly 500$ and they change the rev limiter to 7200 and also takes off the speed limiter. Plus they re format the gear timing and found that when you slam the gas pedal, the stock ecu actually closes the throttle flap by 20% as it approaches the rev limter. A bunch more info is avaliable at their website technosquare.com - Has anyone re-formatted their ecu? I was looking to do so through technosquare and was curious if the benefits were as good as they really sound?

 

Technosquare ECU reflash is #1 on my to-do list.

Technosquare is the way to go.mine raised to 7500k

 

technosquare should be like #5 or 6 on your list.

Makes no sense to get the ECU if you haven't done your intake/exhaust mods first. Yes, you can always update/re-flash at $150 a pop, but why do it just for the rev limiter. + if you are not in SoCal, it's pain to keep waiting for Mr. Mailman to bring your car's brain home.

Could you physically feel any power difference with the technosquare??? or did it just more or less give you a higher red line to get a little more top end out of it?

 

will this also work on a manual tranny

 

Ya i know it will work for stick to, altho i believe there is a slight difference in re-programming... on the website i think there are 2 different options, one for the auto and one for the 6mt. They are the same price - but to answer your question, yes, it can be done for stick too

 

has anyone reflash their 05 AT yet, cause i heard that the ecu's are different. Also is it safe to rev to 7100, with stock valves.

 

I have a question as well ... When you take your VDC off ... and u brake stall and Launch at about 2k Rpm.... sometimes it feels like, something is hold back all the engine out put... does this mean even though VDC is off .. engine output is still being reduceD? .... HELP! ... is brake stall and launch still the best way for an 5AT to launch? ...
