I'm getting my lift, new wheels and 33's installed this week. I'll need the computer flashed after that and was wondering what programmer is better.
AEV ProCal or the Hypertech Max Energy Programmer? What's the difference between the two other than the Hypertech costing three times as much. I did a little research on them, but I would like to here from all of you who have used these or know someone who has.

Thanks.

 

This issue has been beat to death, but here I go...

AEV ProCal is good to recalibrate your speedo, set the TPMS sensors to a different PSI or turn the system off, gear ratio change, plays with headlight controls, has a hand throttle built into it for higher RPM uses (OBA, winch, etc.), and a bunch of other uses.

The Hypertech does close to the same with the tire size and gearing change, but it changes shift points if you're running an automatic transmission and adds some horsepower and torque to your JK, utilizing premium fuel for optimal gains of course.

I had both, IMO, I love the AEV ProCal way more. I run a 6-speed, so the shift points don't matter to me for the auto tranny. The power wasn't THAT noticeable and I didn't want to be running premium fuel all the time.

The AEV ProCal does it for me. I turned off the TPMS system entirely and recalibrated the speedo for my tires. I use the hand throttle when I winch and run my OBA setup. Plus, it's a lot cheaper.

 

I have the AEV ProCal and it works with out any problems. I have been able to program my speed to with in 1.5 mph accuracy at 75mph and 100% accuracy at 45 mph. The steering angle sensor/alignment mode provided the ability to get a far better alignment that greatly reduced steering wobble and my steering wheel clear view is dead on center. In addition the idle control that works with the dimmer switch makes one man winching very easy and I am confident my battery is not being over taxed. The AEV ProCal has been the best $130 some dollars I have spent on any vehicle I have even owned. Great, great product.

 

I thought the AEV would recalculate the shift points on the auto, is that wrong?

 

It does change them to your new gears or tire size, the Hypertech, I believe, lets you change them manualy.

 

Yes the automatic transmission shift points from the TCM are based on input from the wheel speed sensors. I understand each wheel has a speed sensor that works with ESP so the module sets things up to like stock conditions as far as transmission shifting and ESP functions are concerned once alignment and speed correction are completed. When I put my 37" on the speedometer was off by about 11 mph at 75 mph speeds so the vehicle really was a dog and downshifting required excessive driver input. With corrected speed calibration I found a great improvement in shifting and fuel mileage.

 

Got and installed my procal last night and it made a world of difference with the shifting.

 

4whln have you played with the alignment at all?

 

Just read both company's claims and Hypertech claims more horespower and torque - AEV does not. So, if they are true, I guess it's what your looking for from a programmer.

 

What kind of gains are Hypertech claiming?
