Hondata

you can't see in datalog thats posted where it shuts down my trottle, but if you zoom in you can see where it starts to drop my trottle down by itself, remember that is not me letting off the gas, the car is sencing something wrong and is doing it for me.

knew I was going to get this :)

datalog and run tune attached.

car is a 00 si. b16a t66 turbo fully build engine, crower cams/valve trans, using s300 on p28...problems listed above.

thanks guys and sorry about the first post..

I'm having an issue, at about 26psi 440hp @ 8500-8700 rpm the whole chart on datalog is telling me that i'm letting off on the trottle to about 0-5% when i'm not, and ofcourse it's running lean at that point, VERY lean. then right past that rpm it goes 100% trottle again. but I can't risk the engine ...

check your timing, looks kinda low, and second are you running dsm 450?. 2nd gear or 3rd gear pulls and what tranny.

going back to the dyno soon?

You will have to put it on the dyno and measure the power output vs timing changes and see what makes good power without detonating.

ok, i'm not making no power at 19-20 degree @ wot and the car has a miss right at full boost, when I turn the timing up to 30-35 degrees @ wot I make alot better ...

i am on a dyno, like i said i'm seeing 19-21 dgrees. but I want to know what is the starting and safe points, cause this engine does not have a knock sensor.

just wanted to know what is a safe timing for a boosted single to be running at wot? didn't find nothing doing a search. mines is at about 19-21 at wot @ full boost (15psi) I know different cars need different timing but I just need to know if I can turn it up anymore without causing detornation? i ...
