ok so ive got a performance exhaust . apexi induction kit and a impul racing ecu what do i do now to improve the performance. the impul was allready fitted to the car so ive no idea of the state of tune of the motor. its got no bovs and is running standard boost. i think?:D

up the boost!! :D oh, & you'll prob need an uprated clutch once you do this

Boost gauge :) then up the boost hehe,

will i notice if i up the boost and how much do i up it too. how do i do this?:confused: :D

2 ways:

 

1 - cheap way: boost jets, buy 2 1.0 / 1.2mm mig tips & insert them in the wastegate pipes.

 

2 - flash way: buy a boost controller & fit it

 

about 14-15psi is about as far as you want to go on stock turbos/injectors

 

like mike said, you need an aftermarket boost gauge as the stock one is sh!te

might be an idea to do your clutch first as most seem to say they melt after a couple of weeks (days for some!)

You are the only other person I have come across with an Impul ECU. I have a complete 1990 Impul 932S and have been trying to find out what Impul do to them. I am about to have a look at the EPROM to see what the timing and fuel maps look like. I'll post the info when I get it.

nice one:D no one seems to know anything about this ecu:confused: look forward to your reply:cool:
