FIT increasing rev limit

[Mikey1982]

Hi all, I am running my 1999 audi a4 1.8t in FIT mode and is running fine, I want to increase the rev limit but unsure on what effect this will have on timing as I assume the ECu will not have a timing table past the factory rev limit? just dont want to blow anything up,

Thanks

Personally I was reving engines over stock rev limiter several times and there was absolutely no problem with ignition timing. Sometimes 1000 - 1500 over stock fuel cut, there is factory ignition cut rev limiter.

Thanks for this and tried it, goes straight to an ignition cut or no timing, not sure which, do you think if I set timing on the det3 it would work? Cheers

you have a very old bosch ecu....

just open up the ecu, desoldern the flash chip, read with eeprom reader and email to a tuner to raise rev limiter.

problem solved. cost of this +- 75-125euro to raise rev limiter.

if you know somebody with eeprom reader should be very easy.

won't work with setting timing on DET 3, because you can only + and - the timing moment. in ecu cuts ignition there is nothing to adjust.
