i dont know anything about those drivetrains, but you can get a lower final drive or get a lower 5th gear. (if available)
can i adjust it with my avcr?
& can somebody tell me the best avcr setup for 1 bar boost?

No you cant adjust any limiters or RPMs with the AVCR.. it only controls boost pressure in general terms. Has nothing to do with MAPS

Tell me what RPMs show on the tachometer in 5th gear at 100 kph. Also, indicate the tire size please.

RS2 is an RS with a few features from the GSR added, sort of midway between the two models.

Do you have manual or electric windows? If you have manual windows you have an RS.

If you have electric, do you have TD05RA-15GK2 or TD05HRA-16G6 turbo? (Turbo will have a stamp on it).

The 15G is from the GSR, the 16G is the RS2.
in the turbo it says TD05HR,
& yup hve electric windows
so my car is a GSR which means if i do power launches around 4000+ rpm my stupid diff gonna break.. cus it has AYC.... am i right???

It will only break if you dump the clutch... proper technique is to let it bite and slip a little before coming off.. Ive done plenty of launches in my car with ayc and I think Im a little over 400 whp... Havent broken a rear diff yet.... G/box on the other hand

you should be fine

If 5th gear tops out at around 5000 RPM, your car is limited

You are correct, I thought that all evos were 16G (excluding GTA variants), I'm afraid I fell to an unreliable source.

I have put an edit in my post to correct.


OT: Just finished replacing my driveline fluids with Motul products. (I remember reading you use them). Dam that competition gear fluid is thick!

Also worth noting that the speed limiter is only used in 5th gear.

When i had mine on I'd get the ****s because 5th gear was effectively useless. Every time i changed into 5th the limiter would cut in straight away.

apparently, this is an easy fix. should take it to a garage & try to get it removed without replacing the ECU..

Speed cut defender is hardware (like a boost controller or turbo timer), you wire it in and you're good. You should be able to delete the speed cut in the ecu by raising to it an impossible level, ie 500kmh. It's part of your tune, you can get the cable and software and do it yourself or you can take it to a tuner and pay them to do it. You might even be able to get a tuner to sort it out through email, but you will still need the cable and software.

I think you need a 2.0 cable for EVO 6 (check that on evoscan.com) and you will need ecuflash and maybe evoscan to pull the rom.
