Hondata

On the dyno again, graphs looked similar to what we posted before! We checked fuel pressure on the guage and it is around 95 to 100psi when we hit full boost which is around 4000rpm. and then it falls off when the wastegate opens at about 4300rpms. Almost like it cannot gain any more power. Does any...

Any other suggestions, the cat is clear and I still have the same problem!!

Did you change the settings on the s 300 from your stock sensor to the 3 bar map sensor setting? And did you use the right setting? Using the wrong sensor on a stock setting would cause the car not to start!!

cool

yes, just use the msd map sensor setting it is the exact same sensor with the exact same reading as the gm map sensor!!

The power is droping off when the wastegate opens up around 4500 rpm.
a clogged cat would cause something like this to happen?

boost cut settings are set cold 10psi and hot 16 psi, air fuel is at 11.9and maybe a tenth or two lower when it occurs!!

today we tried agin and are still dealing with inconsistancy. Check out these three consecutive dyno runs with no changes to hondata. 1st run is red, second is blue, and third is green

Any Ideas?

I can't figure out what the problem is while tuning for boost. It is a d16 civic with 8.5:1 compression, using hondata and the fuel system is sufficient. While trying to tune for 5psi boost, it keeps falling on its face alittle after or before 5000 RPM no matter what I do. What is really frusteratin...
