How to tune 800whp
#31
Off topic kinda...
So this is probably a really basic question and I just don't know where to look, but how do you guys tune load that high? With my setup I'm hitting loads in the high 300s, beyond what is listed in the ecu, so I'm not sure what to do to tune those higher loads.
I'm not even sure why I'm hitting that much load, my car according to the virtual dyno isn't making that much power...

Seems to work good for traction control and happens fast enough EGT doesnt move to fast or at all. My car I have taken MIVEC out, some timing, all in the pursuit to maintain traction. Need to run my R Comps all the time if it wont sort itself out. I'd never do something so simple as drop the boost

next time you need something like this go to google.com and type in your question followed by evom after it and it will categorize every thread on the forum for you with your questions already answered.
like: site:forums.evolutionm.net how to rescale map evom
http://www.google.com/#hl=en&q=+site...de53b2ade8e603
so maybe your maf needs rescaled or the screen is no longer in it etc. can make it ready higher then normal.

I think Aaron mentioned that the car lites up the street tires so timing was low (real low) at peak TQ. Conversely, Aaron whats the most timing (peak TQ) a built motor can handle (and likes) on a 2.0 with 9.0 comp. on C16? I know these things vary but would like your opinion if you dont mind sharing

Nice power, but why go to all that detuning work to get traction when you can use RPM and gear based boost? It would put less stress and heat into everything.
This log shows pretty well how lacking the speed of evoscan is. Time to start using that DMA logger if you want meaning full data. It is better then the Hydra though. On an 800HP car, a 4th gear pull ends up with 500 RPM steps between data.

tscomp, I think that record can be broken. I was at 705awhp at the time and boiling the tires and bouncing badly. It should have trapped mid 140's but I only got 3 passes on that setup and our track was closed.
I heard yesterday that the track was purchased and so it may re-open next year. I've got some D2 coilovers and a fresh engine but the clutch/tranny is acting up so who knows when I'll get to try again. It's hard to get the stars to align just right sometimes.

No rest for the wicked actually seems to apply to something car related lol

JB, at 38psi on my old 9:1 setup IIRC it did 460 load, at 44psi it did 493 peak. I don't recall going over 500 load but it's been awhile since I've looked. Currently I'm on 93 octane at 600awhp on the new 10: setup and 365 load for reference. I haven't tried e85 yet.

max i hit was around 536 load looking at my old logs here with 42psi spiking. did you do any scaling of your maf at all? i didnt, so quite possibly thats why mine was hitting so high.
my car was burning quite a bit of oil at that high of boost level, but hopefully that is resolved by the crankcase ventilation system i recently installed. i expect 670-680 in kill mode now since this new motor has about 15psi more compression vs the last. first motor went to waste, trip from pa to oh and back it ran low on oil and spun a bearing. still the old engine at heart using the old rods, pistons etc though.
what are your goals with your new setup?

can make a early torque spike or make it hold flat until redline. the perfect tune would be making max torque throughout entire rpm of course.

ya my car is very well built, not much spinning at all only alittle in 2nd depending how slick the road is. its never been to the track tho so i cant say its going to be like that at the track. everything throughout the entire suspension is redone. bushings, wheels, tires, mounts, custom coils, etc.

same ole goal 9.99 @140+ in a really comfortable daily driver. It's funny, I went 10.41 @ 135 on 93 octane and 600awhp but with 700awhp on e85 I went 10.45 @ 139.8 to give you an idea how horrible the suspension/traction was. 100 more awhp and I still couldn't get it done pffft.

i know you were taking some very fast/quick bikes with your car at 700whp.
hopefully you will sort out the clutch issues, that has to be a huge *****.. the transmissions more pain in the *** to pull then the entire engine imo.
