Early 99 ECU and chip advise needed
Ok, so here is my ordeal. I have an early 99, I THINK the truck has the factory computer from that year and I THINK the chip that came with the truck was burnt for a later model like a 01 or 02. Only suspect this because the truck just does not seem happy with the tunes, driving behavior, shifting, running quality ect.
I used to have an 02 and I was much happier with the way it ran.
After reading around I have seen that the PMT-1 ECU seems to be a favorite? I would love for my 99 to run similar to my 02. So, my questions are: will the new computer achieve this? I do plan on getting a new chip or sending this one to TW and having him burn new tunes on it, with that being said would it be better to buy the new ECU and send the new unit and the chip to him at the same time to ensure all programming is at peak compatibility? From what I understand the injectors are slightly smaller on the early 99's, so if I do install a new ECU and a chip programmed to be similar to a later model will the injectors perform enough to support that switch?
I have emailed Jody and he assured me that he could write good tunes for the ECU I currently have so that is definitely an option as well.
I guess my goal here is to get this rig running very similar to the manner in which my 02 used to perform. Not just at WOT, but at idle and normal driving situations as well.
I have the basic support mods, CAI, straight exhaust, zoodad.
All insight is welcome!
