Put the EVO on the dyno down at Torque Freaks today and made some good #.

Thanks TF for the dyno time.

My Log from the 401whp. As you can see I am using all the 780's but its just enough fuel so I am happy.

 

That is amazing!

 

Very impressive!! I wish California would get their act together and provide us with more availabilty of E85.

 

Sick man. How come you have it leaning out to 13:1 near 7.8k?

 

One more thing, are you using the stock actuator?

 

What's wrong with the torque? The WHP is great, but why is the torque so low when running 27psi? The torque actually climbs from where it normally peaks (3800) to where it actually peaks (5200) It should be higher than the WHP at that boost level, but I do see that you gave it 0 timing at peak boost. Is that on purpose?

Also, did you notice there was no change from 5600-7600rpm between tunes? The 10 AFRs made the same power as the 12+ AFRs. The only power gain with the really high AFR is in the early/mid-range. I suppose you needed to go with the leaner setting, though, to alleviate pressure on the injectors.

 

I beleive you are well over 100% on your duty. 20ms at 6000rpm is 100%.

 

wow does seem a little on the lean side

 

Much more timing in the boost spike and it likes to knock so that is just the way it is. On my 1st few pulls when I start at 2800rpm I was geting a good 4-6cts of knock upto 5k. Starting at 3500 really made for less knock that you see in the log.

7.8k is the revlimter which you can tell in the log.

I had it in the 10s from 3k-4k to help with knock I was geting on the street. So I kept leaning out under 5k till I got them in the low 11s which less knock. I really want it low 11s all the way but above 5.5k is all my fuel.

This dyno has allways had low TQ # for EVO's also. I know if I were to dyno 4th my TQ would be a bit higher.

That's AWESOME!!!

 

Nice number's !!!!

 

looks a little lean, but none the less nice #'s

 

Up top on my AEM WB it is 11.9-12.0. The dyno wb is not allways dead on.

 

So on E85 you tune 12:1, I thought since it has a different stoich (lower)than gasoline the target airfuel for a turbo vehicle would be different, lower. Not sure just asking.

 

From all my reading and tuning the E85 on a gas WB tunes about the same as gas.

I have found on my gas wb the E85 will cruse and drive nice at 16.0AFRS.
