Well you'll want to transition into it. You don't need to be 11.5 @ only 5 psi of boost.

Fueling is key with 91 because the stuff sucks and evo knock sensors are really sensitive.

1 count of knock isn't going to hurt, if I see knock in 1-3 counts in spots I don't worry too much unless its all over the place or consistent. 1-2 counts is ok in spots.

I'd shoot for 25-26 on pump gas.

 

I have to ask this, where did you get your car dynoed at and did you dyno 328.6 corrected or uncorrected? You aren't making the power you can be making but if your original dyno was at 20% correction factor then you need to throw that number out the window... It was closer to 273.8 hp.

I ran 26 psi safely for 8 months on 91 octane, of course it tapered to 20ish psi by 7k.

 

So afr should be 11,5 at peak boost? That's what I have been shooting for, thanks for the info!

 

Burque!! We should grab a beer sometime. It was at pro power dyno and it was corrected. I thought vdr 5.7 and virtual dyno were corrected numbers as well, no?

 

Speaking of being a Nancy , how come your log only shows upto 6800RPM? Is that all your pushing it upto? If so, why not try going up to 7600RPM.

Also, what do your MIVEC maps look like?

 

I rev to 7 grand most of the time. It didnt seem worth it to go any higher since boost falls off, am I wrong here? I use the jdm mivec map, it there a better one to use?

 

If you ever have any questions while tuning or anything pm me and ill give you my number and we can talk or text over the phone.

 

Thank you sir, that would be great! Pm sent! I was hoping to get the injectors and pump in today so I could turn up the boost! No such luck...tomorrow will try again! Thanks again, look forward to talkin to you.

 

You can get a good idea of that using the dyno sheet. My max HP is at 7250 and it stays high until 7600. Notice how your HP is still rising at 6800. I think the JDM MIVEC map was the best, but it can still be improved upon. Good luck!

 

Sounds like you are running out of fuel. Those injectors and pump should make a big difference hopefully

 

The logs don't show a lack of injector. 89% is a little high, but the O2 readings are still in line. It's impossible to know for sure whether the ecu is pulling any timing without logging both timing actual and timingmap.

Your actual timing is probably ok around torque peak, but it doesn't ramp up quickly enough. You have to be careful. I have my doubts about most of the 91 gas in New Mexico. I'm suspicious that it's really only 90. I've definitely seen the same trucks supplying philips/66 and shell in ABQ and they list different octane on the pump. I should post a picture of the shell station in tucumcari. Premium is 89 R+M/2! That's right, 85/87/89!

anyway...

Your load values are very, very low. Where are you reading the "21 psi" from, a MAP sensor or mechanical gauge. I don't know why, but most of the gauges I've seen are off at LEAST the 2.2 psi difference between here and sea level. You can run a lot more than an indicated 21 up here. With our thin air, you'll want to crank it up to help widen the power band. It's going to spool up late and fall off early. It's not uncommon for E85 cars to make peak power by 6000 RPM.

EDIT: If I can remember, I'll post a log of my evo 8 with intake, cams, exhaust, stock turbo, and 91 from here in NM.

 

Here's a random log of 91 octane gas in my car in ABQ, NM. This is NOT an example of a finished tune, but a random log while scaling my FIC 1050 injectors.

Mods are: perrin intake, Helix cams, megan o2 housing, 3" exhaust, walbro 255, FIC 1050 injectors.

also do you have any exhaust leakes pre wb02?

 

What are the different temp. parameters? I am currently seeing about 114 to 120 intake temps with ambient being 103... My ecu is pulling about 2-3 degrees of timing with no knock. I ended up bumping up my timing to compensate the loss and will be doing a boost leak test tomorrow, but this still is annoying.

 

ignition trim vs air temp - zero everything out from 93 to 122. No need for the ecu to be yanking timing like that. and dangerous to compensate for it, because when the weather changes your tune will be off by a high margin.
