I think it is a good idea to adjust your MAX MAF higher so you will only be at 90% load site at redline. That will give the UTEC more room to run in a proper cell when teh weather change enough to affect the amount of air being sucked in (read 100% load site).

You need a bit more fuel between 4500-4750.

Seems like you are running in 3rd gear... if you are running stock turbo, it seems to spool a bit slow. You may want to try to "decrese" your gain by 1-2 point. But becareful that it will affect your boost level as well.

I envy your timing curve though. With 91 octane, I am riding on the knock threshold at 13 degrees, 20 at 7000 RPM. And I could only have around 5.5 deg between 4250-5250 RPM.

it is the stock turbo, and i dont know why it spools slow. I have a Halman. It never used to. I plumed in the TXS bleed valve on the Halman thinking that if i bled air off of the wastegate line, it would stay shut longer, but didnt seem to make a difference. Ime pulling 1900 Hz of and and the car runs very good, but the boost ramps slower than the EVC 5 i used to have.....

You don't want the bleed valve (ABC) when you running Hallman. I think that's the problem.

Here is the log without the TXS/ABC. You see, the theory is that if you were to increase the hole in the Halman, you would keep the WG closed tighter longer and increase the boost ramp rate. So instead of drilling out the small hole in the barb, i just plumed in the ABC and could effectly adjust the bleed rate. It worked soo well for Abner, he get a CEL everytime he boosts because he ramps too fast. Mine didnt. Anyway here is a log that i started the morning out with WITHOUT the ABC

I'd watch out on that Injector Duty cycle.. hittin nearly 90% is to close in my book...

Talk about injector duty cycle. I see your signature saying 780cc injectors. i thought it should be big enough even for some big turbos? I was wondering how you are running at 90% duty cycle at only 11.49 AFR, 18.2 psi @ 7400 RPM.

I have the stock injectors, but I only hit 89% with 11.0AFR, 20psi @ 7200RPM. Someone pleae chme in... or I will have to look into a replacement of my oxygen sensor (I use LM-1).

I definitely find my boost spools faster than that.. an MBC pretty much shuts off the signal to the actuator until the ball-spring tension is met, then it sends the signal to open the actuator, so in theory spool should be as quick as it gets... Is there some sort of restriction going on somewhere? I get that CEL also when the boost comes on.

Your injector duty is actually pretty high for 780cc injectors, but that may not be an issue, just tuning..

Here's a thought, as the boost ramps, you very quickly hit 11.5:1, and you have aggressive timing, what if you try running 9 degrees of timing, and lean it out a bit at lower RPM till you hit peak boost/torque... That may get the car to spool faster..

my bad, i havnt updated my sig in awhile. They are stock injectors......I just cleaned the halman and the BOV. It was quite gummy. Ime going to go do another pull. If the boost ramps slow again, i will clamp off the WG line. If it still ramps slow, maybe a weak WG spring?? More in a few hours....Ray

o.k., well ime stumped. I disconnected the WG line and did a log....Here it is. How is it possible that it ramps up so slow??????

You think 90 is bad....i once had 99.9...then - - -...i think the injectors stayed open!

ray, i have a theory...dont know if it'll fly......its really humid right now.....atomic weight of water H2O = 1+1+16 =18, nitrogen = N2 = 2(14) = 28. Since air is 78% nitrogen, 21% oxygen, ....the water in the air is making the atmosphere less dense (barometric pressure always drops when it is about to rain), less dense air = less/slower boost.

18/28 = 64%...the air is only 64% as dense as when the air is dry...also, sahuarita is higher elavation, so it doesnt help too.....

Thats possible with air density and elevation.. also your wastegate may be opening (not enough preload on the actuator).. Another not so happy possibility is a problem with the turbo, maybe a bearing or lubrication problem causing it to not spin as easily.. Don't know how you would test for that though.. Another possibility is a leak somewhere or the MBC is gummed up badly that its always open slightly..

FYI. You are giving up a lot of HP running that rich in the lower load sites. You should be reaching your target AFR by peak torque but not at tip in. If you lean it out below 5K you will notice a difference. I tested this on a dyno recently and I was able to pick up 15HP and the response is much better. Even the factory runs ECU runs leaner in the lower RPM. Maybe Jack can elaborate a little.
