What's your take on etuning?

It works just as good as of they were street tuning themselves as long as you don't screw up while collecting data. -
Very popular on the Evo and Subie forums. There are some very knowledgeable tuners out there who are good at it. I think that they have the ability to get your car running good but the downside in my mind is that you don't have a dyno to back up whether your car is really running to its fullest potential hp/tq. Also you will need to set the car up for your e-tuner and have a way to collect data. You'll need to get a wideband o2 sensor setup and then tie it into whatever system you use for logging data(cobb accessport, accesstuner race, evo scan with a tactrix cable...) I'm personally using an accessport with my wideband hooked up to it.
It seems that they are also charging about the same or really close to what shops would charge for a dyno tune. If you don't have a dyno tuner in your area then an etune can get you running safely. If you do have a dyno tuner in your area that is reputable and the difference in cost is $100 or less I would go to the dyno tuner.
On the Evo side the big names that come to mind are Chet Rickerman and TJ Van Cott. Based on all the vouches and all the work they post online they seem quite knowledgeable and I wouldn't hesitate to let them tune my car.Comment

Hondata offers 15 etune exchanges for 200 dollars. That's a lot of street tuning. You will almost always need a dyno for spark tuning. But the dyno tune won't provide near as much street tuning or sometimes any at a competetive price to etuning.Comment

I'm contemplating on either doing a dynotune or e-tune. I'm getting into a lot of data logging. Eventually I want to get into tuning myself. I'm really checking up on the flashpro.Comment

You need both. Etune is a cost effective way top tune for, drivability, fuel economy, and conditions under 75% throttle. Dyno tuning is required for peak power from spark tuning.Comment

I ASSumed you were talking about the evo, what kind of car are you talking about?Comment

Nope civic siComment

I'm assuming they will pay for damages if they send you the wrong file and you're trying to drive your EVO with a map from another car. That's the only part that worries me. That and live data cannot be seen to determine hardware faults (ie - stuck waste gate springs)Comment
-
They don't do that lol. You collect the logs on your own car. You send it in. They adjust the maps and send it back. Then you log data again with the new map and repeat the process as much as you want. If you have the ability to log the data they need to etune you will be able to view what your car is doing as you are loging data.Comment

Yes you can view live data as you're logging it. If I'm logging WOT pulls I usually display Boost, Knock, and AFR while in the background 10-12 other parameters are also being recorded.Comment

Which AP do you have? I thought if you ran AFR with the AP you had to log that separately and then link it together in AccessTuner Race? That's at least what I needed to do for the APv2 and AEM UEGO.Originally posted by Chrisisiced View Post
I had mine dyno-tuned so I haven't build the DB9 connector for my UEGO. I usually just monitor AFR visually at full boost and watch my FBKC when I'm driving to see if anything pops up. I've been lucky as it's usually zero unless I hit a bit of noise transitioning into boost right when I first get on the gas if I'm just cruising along.Comment

I can't really help you fully because you're on the STI side but.... I have a V3 AP on my Evo. Surprisingly this is not covered much on the forums and is difficult to find the little info that is out there but I removed my rear O2 sensor and replaced it with the AEM wideband sensor(which is in the cat, not ideal I know...). I cut the plug off my original rear O2 sensor and then spliced in the aem 0-5V wire (forgot the color) to the oem signal wire and plugged this back into my car harness. Because I only spliced in the signal, the car would throw heater O2 and other O2 related codes but does not affect performance in any way as the rear is only for emissions not altering engine parameters. If you have access to your map you can turn off the codes in accesstuner race or if your map was made by a pro tuner you would need your tuner to disable the rear O2 for you as the pro tunes are usually locked.Originally posted by AccordWarrior View Post
By connecting the AEM 0-5V to the car's oem rear o2 signal wire the car AND AP will now see the signal from the wideband. To add complexity to the issue, with this setup my AP would read 0.5 richer than the aem gauge. It turned out that the rear O2 harness needs to still be grounded and after grounding it the AP was very close to what the AEM gauge was reading. I can't explain why this happens but I managed to find 1 thread on it and I learned about grounding the harness to get the correct AFR on the AP.
With all that said, most people are building that connector that you mentioned. While I could have done that, I wanted the ability to log on the fly without having to carry around a laptop.Comment

When I was still using my evo I kept all my sensors and got the wideband uego from arm but got the defouler from vibrant and the issues stopped from my tune.
I never e-tuned with the evo but I did etune with the flashpro. It could be better but I need to go to class to tune. I know once I do this and finish my courses I'm definitely gonna go for more and eventually charge for it.Comment

More on my datalogs
Datalogs
These are my datalogs from getting an E-tune by the wrong person. honestly I could have done better myself. Which is why I'm trying to learn how to tune but I need to find someone who does it for a living and study them.Comment
