Ecm/tuner problems

[Brown1018]

I recently joined the stroker crowd and swapped my 4.0 for a 4.6 Titan in my 01' Tj. Was having fuel issues due to stock injectors and finally switched to 24# Ford injectors. Noticed that I started having stalling and misfires along with starting problems, all symptoms of a faulty ecm. I just ordered a reman 4.0 ecm programmed to my vin from car computer exchange. The ecm is plug and play but I'm expecting there to be issues because of the programmed ecm will think it's running a 4.0 instead of the 4.6 stroker. Is there any break in methods or tuner/flashpaq one could purchase to get this thing running smoother or will the new ecm be just fine the way it is?
Thanks

The '00+ ECUs are more finicky than previous generations so ideally you'd be better off going with a custom tune. Shoot an e-mail to Chris Jensen at [email protected] . He's a busy guy so he may be slow to respond, but he has a great reputation for tuning Jeeps.

I don't foresee this being an issue with the 96-98 ECMs, which is probably one reason I've never encountered this problem. Another reason may be that I never had any experience with a stock 4.0L and I jumped straight over to the Bosch 280155703 injectors commonly found in Dodge Neon and Plymouth Breeze passenger cars. What are some of the readings you're getting with your current tune?
