I am looking at purchasing the pro version of HP Tuners so I can hook my wide band up to it.
The car has a 2.4 LE5 motor and turbo. The car has a Trifecta tune that I would like to remove and tune myself. The tune is ok the car runs good, it is just a little rich under 10 psi boost gets down to 9.8:1 and starts to misfire. I would like to get the AFR to 11.0:1 and see how she does. I purchased a spare ECM in case I really screw things up I figure I can stick the original back in the car.
The spare ECM I purchased was from another 2.4 le5 motor with turbo, the tune should at least run. The spare ecm is what I want to hook HP tuners up to, leaving the original ECM untouched for now.
Looking online using Google it looks like I can fix the VIN to match the car so the BCM does not have a fit.
How hard is a new MAP sensor to program 4 if I have the part number and can find spec sheets online? It is a two bar sensor.
Can a person who understands programming such as visual basic from college and is computer literate get this tune dialed in for a weekend street driver?
I do have a technical background I spent two years in college to be an Automotive Technician way back in the late 80's early 90's. EFI was just becoming a reality and throttle body injection was more common. I went in the Navy an learned to work on Radar Systems instead.
The reason I am thinking of doing this is I can't find a tuner locally in the Rochester MN area that has experience with my car. I figure if someone has to learn it might as well be me. Anybody here in the Rochester MN area that can help and would be willing to help.
Should I by HP Tuners Pro and pay someone like Performance Autowerks who is familiar with the setup to do an initial HP Tuners tune? Or is that going to be a waste of money?
I want to experiment with a few tunes 92 octane fuel, e30, 93 octane with water methanol injection, and e30 with water methanol injection.
