I forgot to add I have a 2001 jeep grand Cherokee 4.0L inline six, it has a cold air intake and a straight through muffler, no cats, and wider wheels. And dual 8 in subs pulling a few amps.

Welcome! You'll want to familiarize yourself with tuning first, https://www.hpacademy.com/courses/efi-tuning/Originally Posted by Dailyjeeponwides
Next you'll need a wideband sensor and gauge
and finally read this thread! It may not make sense to you now but will when you look at making adjustments.
Anybody else have their short term and long terms conflict and seemingly cancel each other out? My long term is subtracting 10% but the short term is adding 8% back in most cells. If the fuel trims are reset, they'll slowly work their way back to doing this.
Hey all, I'm tuning a new 4.7L inline six in my 98 TJ.
Q: Does anyone have a 97-01' stock map, specifically I need to see what the stock Transient maps (accel enrich mult & throttle based) look like. Mine are all incorrect.
Hey All,
I found some training on tuning: https://www.mmx4x4.com/p-144-jeep-en...ng-school.aspx. and https://www.summitracing.com/parts/tun-4321.
Not sure if they are the same or not, however, they are by the same company.
Anyone have any real world experience on them?
Quick update.
I managed to find an excerpt from the trainings I mentioned earlier, and they are using a 2004 GM Silverado as the example in the training. That doesn’t seem very logical since the training is specifically for a jeep. Why not use a jeep file?
I think I’m going to pass on it
Just wanted to share what I found in hopes that it may help other people
Hey FrE^k,
Here?s my stock tune from 2004 Jeep tj 4.0 auto trans.
Hope it helps!
