I recently got a cable and started tuning on my 2003 evo GSR on E85.
I had midgetspec (witch BTW he has been a great help!! thanks Aaron!) give me a base map for E85 to start with but it ended up not working well in my car since it was based off of a evo9, so I took my pump gas map and re adjusted the map and tuned on it for the past week and this is what I ended up with according to DLL Car weight is set at 3350 total weight smoothing at 5 and NO SAE correction. Tire adjustment is set for 18" rims as thats whats on the car.

I'm not sure how close the DLL app is but atleast I can tell if I am going in the right direction.




9 degrees at peak tq. and 20 degrees up top at 7500rpm, boost is set at 26 falling to 23. Tuned to 12.3 A/F on straight up E85 absolutely no knock, maybe a blip of 1 count on the shifts. So yeah the car is cornholed ha!

Mods on the car

I feel the car still has more left in it. Still tuning on it and looking to get it to 420ish. So far I'm pretty impressed with the ecuflash software. I've been a big AEM standalone nut for the past 5 years, so sticking with the stock ecu had me a bit nervous, but now I think other wise.

 

congrats on joining the E85/stock ecu/evo world lol.

 

nice job. Welcome aboard! I met you at the import races in Boise last year. I was the terribly slow Graphite Grey evo from Hailey. Rockin out on the East coast now, though, and still somewhat slow hehe. I wish we had E85....

 

HA! thanks man, so far I've been having the time of my life in this turd haha. Feels a bit different going from a mid 8sec 1g to this. It's almost like driving a geo metro compared to the talon, But I'm have way more fun in the emo, I mean evo

 

Yeah I remember you, whats up man! Where did you move?

 

Very nice! Timing sounds right, maybe richen up the AFR a tad, you'll find that E85 likes to be a tish inconsistent from pump to pump, and of course come spring/summer it'll lean itself out as it goes from E70 to E85.

 

I always keep the wheel size on 17 and i run 18 inch wheels as well.. If i put it on 18s it inflates the #s alot. I know my DLL when I got my car back from AMS was within 5hp consitantly from there AWD dyno jet when setup this way.

 

Yup, I'm fully aware of that, nice looking out man! I've been tuning on E85 AEM equipped cars for the past 2 years Currently we are on E70 right now since it's been around 40 degrees outside. They made there switch a couple of weeks ago at the stations. I've gone through 4 tanks of E85 and so far the consistency has been good. I keep good tabs on the A/F.

 

I transfered out to my company's Maine office.

You came into the evo world at the right time. I smell big improvements happening in the near future with the stock ECU. For most of the community, Id venture to say that there wont be much need for an AEM-type system.

 

I noticed that as well, but the fuel consumption matches up for the most part via IDC with it set to 18" rims. My duty cycles with the 1000cc's at 12.3 a/f are at 85%IDC. All and all I don't care about the numbers, more less using the DLL app to gauge the right direction with the timing/fuel tuning, so far it's been a very useful tool very impressed with the software so far


(CORRECTION, just looked at the log again, it's at 81% IDC not 85%)

 

Very cool Jake. Ebo's are fun. I was one of the guys who said hi when you made it to MIR earlier this year. The evo 7 bolt is much more detonation resistant than our old 6 bolts. Especially the 9's. You can actually run pump gas in the summer and still be able to pass people on the highway unlike a 1g 16g car.

 

I LOL'd at this because its true... although I can't help but think some of that was due to the SMIC

 

Glad to hear that you are up and running Jake. Between the 2 maps (pump gas and E85) I might not have had them labelled correctly and there was the confusion.

Remember its not so much about timing at peak torque since you'll be over that at the strip anyway. Makes it fun on the street though I bet. On Lucas car and mine (both on the Green and the stocker) we usually arent able to tack that much in. When I did the initial tune on that car for the last owner it had so many other issues that it may be one of the cars that for some reason has base timing differences the rest of the Evos.

I can think of 2 right off that have exhibited that type of behavior, and that one did melt plugs once or twice even with "normal" timing on pumpgas. I am not sure with the other ones if it was just a cam timing problem or possibly the crank trigger. I do know that on those cars they were about 8-10* off what they should have been (that is they should be 15 and I had 23 in for the same knock threshhold).

 

^^yeah I've noticed on a few other evos down here that I have tuned via AEM that they won't take the same amount of timing. Tony's evo on E85 is taking the same amount of timing my car is right now with no knock. My buddies 03 evo won't take anything close to what we have in mine and Tony's. It goes to show that every car is different in there own way.
Most of the issues I found with mine after I bought it was 3 vacuum lines under the intake were just hanging there, one of them went to the EGR. It would cause problems so I just put an EGR block off plate and cleared the EGR code.

The plugs that were in it were Iridiums, I've seen those melt more often then not when there is any knock going on.
I'm running a pretty cold plug right now, going to step up to a hotter plug now it's on E85. But on pump gas I was running BR9ES plugs. I'm going to slap some BPR8ES plugs in it this weekend since it's on E85.

As far as the peak tq numbers, it does make it for a fun street car, I wanted the most tq out of it that it would allow me for the fun factor on the street. Pretty fun laying into it in 2nd gear at 2000rpm and the damn thing throws you in the seat from the nice TQ.

As far as the maps you sent me, the one E85 map would buck hard and stumble for some reason. It kept having check lights for speed sensor and injector circuit. On 1st onset of boost it would go turd rich and puke and fart. That and Idle it would die at stop lights ect. So instead of changing everything I just tossed my pump gas map back in and re-adjusted it for the E85 and it's been working like a charm! Not saying your map couldn't have worked, it's weird cause most of the scaling and such is pretty close to what my map is, but it acted completely different, weird. Might have been something to do with when I downloaded it from my email? who knows. Oh well. And thank you for the modified ROM for the NLTS items and such.

I'm able to add a tad more timing in then you guys cause of the elevation difference and hardly any humidity over here, maybe 10% at the most, we sit at 3000ft. as to your sea level and high humidity climate, so I would suspect that would have something to do with how much timing you are able to toss at the car.

 

I was able to tweak on the tune a bit more this weekend. Smoothed out the fuel map and ignition map as well. Here are the results, Before it was 410whp 423wtq est.

These are the same settings in the DLL app. as before. Car is ripping for sure, Pretty fun to semi break all 4 loose from a 1st gear roll
