However, that has nothing to do with what KartaRailed said. He said what I was insinuating, which is that the exorbitant cost of an AEM EMS could have been better spent on mods that actually make a much bigger difference on such a lightly-modded car. SS O2, GSC cams, Snow Alky, LICP and a custom reflash. Bham, he'd be making much more power, and the alky would reduce his IJD significantly.
Instead, he got an expensive standalone ECU that requires a lot more money to be tuned, is more of a hassle, can't pass emissions, and now he's worried about getting injectors. Big waste unless he plans to do a huge turbo and built motor in the near future, but I doubt it since he's talking about his stock turbo IJD...

Those are good numbers anyhow. Congrats. What kind of a Dyno?
Obviously we dont know why he purchased the AEM because he didnt say, maybe he doesnt want to be getting a reflash everytime he mods his car. Maybe the tuner he likes to work with only tunes AEM. Maybe he's planning on going big and he's just gotten started.

Yes, I already asked if he planned to do a big turbo upgrade, because that is the only logical explanation, but he didn't answer. Considering his planned mods after this are IC pipes, injectors (for his stock turbo IJD), and a clutch, it doesn't seem likely...

Eh, no, an AEM EMS and Motec will definitely make more power than the stock ECU if tuned properly. Bigger setups will yield bigger gain differentials, but you definitely can make more on the AEM EMS.
However, that has nothing to do with what KartaRailed said. He said what I was insinuating, which is that the exorbitant cost of an AEM EMS could have been better spent on mods that actually make a much bigger difference on such a lightly-modded car.

Any opinions on my datalog?
Educated opinions are hard to come by.
I'm in disagreement with you on the EMS. Whatever gets you there will get you there in my opinion. If you can get ecuflash to run a solid AF with good timing...and the AEM runs the same, then you'll make the same power. It's just easier to do that a standalone than to mess around with ecuflash. I find ecuflash rather innacurate compared to a standalone...but then again I much prefer and am used to tuning a speed density setup.
but we are in agreement essentially. The money spent on the AEM would have been better spent in other mods.

There's far more to tuning than AFRs. An AEM EMS can -definitely- make more power than the stock ECU on the same car with the same mods. It's not an argument - it's a fact.
I don't have a comment on your logs - I can only see up to 6k, and it looks fine to that point.

For me it woudnt be any different. Actually it would cost more but then, I dont have an AEM and I'm not swinging from AEM's nuts either.
Yes, he will have to get the AEM retuned as well. I never said it didnt - please dont put words in my mouth. I never said or indicated that it tuned itself, and yes it generally costs more to get AEM tuning.
Ultimately, it's not my car, I dont know why he chose to go with a standalone, nor do I really care. However, It's annoying when people assume too much and dont have anything nice to say and criticize people instead.

I'm not a professional tuner...and I'm always looking to learn more. I appreciate your time and response.
Aside from setting proper AFR and timing, how would you make more power with an AEM aside from perhaps using a different ignition system?
Say you datalog and you run the same AFR and same timing with ecuflash and the AEM EMS...do you think the AEM EMS is capable of making more power with other adjustments? If so, I'm wondering what.
In regards to my datalog:
You were saying that the stock injectors are capable of more than 22psi? I'm curious because I've always thought that the evoscan injector pulsewidth readings may be off somewhat.
What do you think of the AFR and IDC here?

maybe a little lean around 3500 (bring the 11.8's to 11.5). Also have you tried not changing your timing through that area. - maybe not decreasing it till the 260 column. I've noticed sometimes timing changes initiate low knock counts that could have 0 knock if the timing was left alone in that particular cell and increased on the next cell after the boost spike.
200 220 240 260 280 300
6 6 6 5 4 3
7 6 6 6 5 4
8 7 6 6 5 4
9 8 7 6 5 4
Looks pretty good though, but I'm sure your shooting for no knock.

Thanks for the advice. I'm curious about injector duty cycles at high rpm. Any comments?
