Remap Issues

[AFTDRK]

hey guys,

i just had my car remapped yesterday using an RB20DE ecu out of an A31 cefiro.

the car feels a little more powerful now (mild mods: exhaust, fmic, turbotech boost) and was just shy of 200kws on the dyno.

a few issues have come up though,

1. when i start my car 2 out of 3 times it will start and then die down and stall.

2. it idles quite high around 1500 rpm cold start, 1000 when warm

3. strangely when i put it into any gear when stationary the revs will increase a few hundred rpm.

4. the exhaust temp/cat light flashes randomly while driving

any advice, opinions or theories will be well appreciated

I personally wouldnt have gone to a RB20DE ecu...you do know that your loosing your VCT or whatever its called by doing that....i have heard of people actually going to Z32 ecu's for RB25's remapped...

Talk to Jeff from Speedlab or whoever did the tune for you mate, they would know the car better and prob be able to sort it out for you as well

who did the tune?

jeff from speedlabs

then take it back to him and let him know what is going wrong mate

Jeff will sort it out just take it back and he will fix it. For the cold start you might need to leave it there over night though.

I had my rb25 remapp from him. i used a r32 chip and the onli thing i had problem with was when the car was cold it would do the same thing, rev at 1500rpm but when its warm its normal at around just under 1000rpm, he said something about i had an external blow off valve. =]

Prob just needs a cold tune as well mate....my mates 33 had a power fc in it and it did exactly the same thing, got it cold tuned and never had that problem...and you would notice that the car literally goes nowhere unless its warmed right up....sucks if you wanna leave in a hurry
