The boost doesn't matter at this point. It won't run in the upper RPM range at all because it's so rich... I will get to it, I just haven't had time to work on it since monday... I will get around to it on monday again. It's just a pain in the ass.

But the boost is spike 23 and 18 at redline... 91 pump gas, no meth, no knock.

Yes, it is a pain in the ass, and one that is likely driving you pretty crazy having to drive the thing to work and back every day, gettting smoked by hondas no doubt..... I was going to say, just put another pound or two of boost on it for the time being, but 23 is as far as I would go with boost. Unless you can get that thing to hold more to redline. But I guess you are not seeing a whole lot of redline these days.... I'm just F'ing with you.

I won't be that hard to fix.

Are you still running the 180 degree stat? This is on a completely unrelated subject. Just wondering what you have tried to bring back fuel economy beyond putting in the stock stat.

I have a flash that I am quite certain will fix that.

I am just running the stage 3 torque table right now and that's what it's run. I haven't modified the torque table yet because I need to get the damn fuel right first. I have a tune in right now that's way off, but it works and I can actually ride it out to 6500... AFR are low tens to less then ten at WOT... But that's fine for now. I just want to get the fueling right. That's my main concern right now. The car is still faster then when I had the E1 and meth LOL... Still running the 180* stat. Fuel eco will be fine once it's fully tuned.

Did you cut and paste the stage III torque table to the stage II tune?

For me, scaling for 750's nailed idle, part throttle, and cruising (all fuel trims stay very close to 0), but left me rich at WOT. I just removed fuel for WOT through the VE Bank 1 table based on my wideband logs at the track. IIRC I pulled about 20% from 3000rpm on up to get it from pegged at 10:1 to a nice flat 11.5:1 at WOT.

There may be a better way to do it, but that's what worked for me. Then again, I have a unique vehicle that I'm tuning here.

It's the Stage 0 tune, totally re-worked. Cut and pasted and then some... Some of the stuff I had to manually rescale.... Some of the stuff you can't cut and paste. You have to actually just re-write it manually.

I am going to try and get the injectors closer... Then I think I will pop it out the VE table... Thanks for the heads up.

In case you need it, heres the calculator:

Injector Flow Conversion Calculator by NickFury

Scaling the injectors properly made a world of difference for me, I'm also not running a RRFPR.

thank you. That's how I calculated it, but I am just having a hard time getting it nailed for some odd reason. I think the injectors I have flow totally different then the stock molar injectors. I also think from the factory and in the staged kits that the fuel trims are off.

because the VE of S0 and S2 are different...if i understand correctly
they should be the same since you didn't change anything to the engine

Running the S2 VE Table I was fine for idle and part throttle with the injectors scaled, but WOT was very rich like wannasupra said, pegged 10:1 until I removed 20% from about 3000RPM on up from the VE table. After that a nice smooth 11.5:1.

I re-tuned and was hitting 22psi all day yesterday doing some autocross. Still need to make some adjustments, dropping just under 11:1 in the lower boost range then hitting 12:1 at the spike before dropping back to 11.5:1. I disabled the coasting fuel shut-off, made for some fast fun autocross.

I am having a strange problem though. Whenever I flash a new tune, it is very hard to start the car again the first time after a flash. It's like it dumps a ton of fuel in and floods it. Takes me 10 to 15 minutes to get the car started up after a flash. Then every time after that, it starts perfectly. Fuel trims at idle are always right around 0 after starting it up, so it doesn't make sense. Out of the dozens of vehicles I've tuned, I've only ever had this problem on this car. :\

Do you disconnect the battery after you run your flash?
