Stock ECU to Elite 1500
So I am almost fully decided on switching to the Elite1500 over the stock ECU - but am curious who all else out there made the switch from the stock ecu to either an elite/infinity/etc and if the drive-ability and smoothness of the car post true ECU change was?
My main reasons for doing it is that I want to run a true flex fuel setup and being native to the Elite(with sensor) just makes sense in putting the money towards a standalone.
In addition the quarkness of the stock ecu is just getting annoying.. Cold/Hot start fluctuations, temp/elevation changes, etc. They all seem to be far more pronounced with a higher HP E85 setup then on my previous setup.
I got to ride in an Elite1500 powered car this weekend.. and it was just so smooth ALL the time.. the AFR's were literally perfect, ALL the time. Etc.
I know stock ecu tunes get you "PRETTY GOOD" but I guess I just want better.
So in short - anyone out there switch from stock ecu to aftermarket - and regret it at all?

I gave the stock ECU a fair chance. I always heard about how people were so happy with the stock ECU and spending money on a standalone was a waste. Then I switched to an AEM EMS and forgot all about the stock ECU. On speed density, I think the driveability of the stock ECU plain sucks compared to a properly tuned AEM. Just the fact that you can make changes LIVE while the car is running makes a standalone worth it, in my opinion. If you have access to a respectable tuner that knows their way around a Haltech, I don't think you'll regret it one bit. I've heard good things about Evans Tuning in PA.

I switched to the Elite 1500 a few years ago, and it's been excellent. The extent to which you can tune the car with it is great, has lots of useful functions, 3-level engine protection, and it's awesome being able to live-tune as opposed to stock ecu. I've had no drivability issues, although transient-throttle was a bit tricky to dial in at first. Drivability issues are all going to come from the tune, so make sure whoever you decide to have tune your car is willing to take the time to do the job right.

After fighting with the Tephra mod and factory ecu, I gave up. I made the switch over to an AEM Infinity and couldnt be happier. Its better then the factory ecu in every way. It runs way smoother and gets better gas mileage. Plus I am running on full flex fuel and its awesome. No map switching, no worrying about having full e85 in the tank, just dump in whatever combo you want and the ecu adjust everything automatically.
Make the switch, you wont regret it!

Elite 1500 is about $1500. I can get a better price for you if you're interested, though, PM me. You will not be able to pass OBD-plugin emissions testing with the Elite 1500. I usually just swap back for emissions testing, swapping ECUs is a matter of minutes.

It's interesting that the Elite 1500 has knock control as a basic feature rather than an add-on option like most aftermarket ECUs! Any feedback about the knock control feature, how effective/programmable is it compared to the stock ECU's? does it work with the stock knock sensor?

There is literally zero reason to get the 2500 over the 1500. Spoke with a tech at Haltech, and unless you have a desire to waste money .. there is zero reason. The only reason shops might push the 2500, is because they get a better price on them as the 2500 can run 4-8cyl, so they can use them in evos, to gtrs, to any V8. There is literally zero other gain beyond injector/ignition control over over 4 cylinders.

depends, horses for courses. if you are going higher power levels and obviously running map sensor then yes a standalone would always be better. standalones also gives you more features and protection that you can all customise and not running off ecuflash definitions which you don't even know if they are accurate... live tuning is also very good.
closed loop fuel control with wideband etc.
elite 1500 vs 2500 obviously the 2500 has a lot more features and helping it future proof for bigger power levels. has e-throttle and more injector controls etc.

May want an Elite 2500 if you want to be future-proof and you want more outputs, as you can reassign the unused ignition outputs to other things. With that said the same can be achieved with a $400 IO Expander unit. I'd wager 99% of Evo owners would be happy with the 1500.
