Title: Revo flat spots
Post by: Pikey Motorsports on March 30, 2013, 05:54:51 pm

had stage 2 done last week, get a very small flatspot at approx 5.5k-6ish

thought this was only a heard of problem on 2+ and the rs4 valve helps but not needed for stage 2?

any thoughts could it be the settings?

Folk may say put a rs4 prv in but to get some learned opinions you will need to post up some logs of boost, timing, N75 duty cycle, rail pressure for hpfp and lpfp at minimum.

I changed my boost setting to 8 rather then 9 and its pretty much gone.

When I was stage 1 I had a similar issue (sporadic) and turning the boost down by one cured it.

I thought REVO had released updated software that pretty much eradicated the flat spot?

RS4 Fuel Valve will not cure your flat spots, you need revo to do a logging session and see whats going wrong.

Your cam follower and HPFP ok?
