Foxbody Mustang Pro M EFI Engine Management unboxing

Overview and unboxing of the ProM engine management system
Review of the harness, the ECU, excellent build quality, the various inputs, and the ProM fuel pressure sensor

This is a great system. Installed it on my '86 last year (injectors, MAF, shutter wheel, O2s w/gauges all from Pro-M) and a buddy has it on his supercharged 460ci. '93 Cobra. We have had no issues and and could not be happier with the system. My buddy ordered a second for another car and another buddy is about to order one for his '93 notch that I will be installing. Both cars with it installed run perfect and it is very straight forward to install. I just ordered the pigtail to add the no lift shift and will be getting the harness for traction control, might as well utilize some of the built in features. Make sure you read the instructions for the wide-bands. Most headers have too shallow of a bung and the sensor needs to not protrude in to the exhaust flow path. (bad for the sensors) You're gonna love it! Put a few miles on after you get it installed and let the system learn (my car would shut off after a hard wide open throttle pull when I would let off the gas immediately, did it a 4-5 times the first week or so and hasn't happened since as the ECU has learned) You get what you pay for. Good Luck!

I'm actually switching to the Zeitronik widebands because the Innovates have had issues reported by other users. I am wrapping up other stuff on the car but will likely have the harness install video loaded next weekend. I really like the mostly plug and play aspect of these system. Time will tell once I get everything up and running.

The quality of that pro m efi system is untouchable. I feel like not many people use this setup but I think its the best option for an efi fox body. I know the Holley systems can be real finicky as far as getting the tune dialed in and plus its map sensor based versus Maf. I was really thinking about using this kit for my 86 fox but I’m just going the cheaper route and doing an A9L Maf conversion. I know it should work out fine plus it’ll just be controlling a N/A 408w I just built thats pretty similar to your engine. Good luck with the build man its gonna be sweet for sure!

Agree 100%.

Hello guys are you able to reflash the pcm with different calibrations at home? Im going from a 91 cobra to 87 non HO 302.

[@MrStangdawg]

Yup you should have your dongle and the software you can do it yourself

[@bobfisher9452]

Thanks for the info on the harness. I just received mine and started installing it yesterday. I couldn’t figure out what the big plug was that you pointed out was the traction control. I’ll be downloading the pdf instructions as well, there were no instructions in the box. Chris emailed instructions on how to download the software. The pdf must be on his web page? As you pointed out very high quality system, I’m excited to get it finished.

[@bobfisher9452]

I do have a question on the Innovate O2 sensors you may be able to help me with. Going over the instructions Innovate recommends welding the bungs 24” from the collectors. But I’ve noticed in a few videos LMR’s and Chris’s video they used the stock O2 sensor locations. Do you have any recommendations for that? I’d like to use the stock locations if possible, just saves some work not pulling the exhaust and welding bungs. LMR noted that they have not had any issues yet with using the stock bung location. I think the stock O2 sensors are narrow band. Maybe they can take more heat than the wide bands. 🤷🏼‍♂️

I'm very interested in this set up amd wondering why no one really uses it ?

[@MrStangdawg]

ProM doesn't have the marketing clout like a Holley. Lot of the support outside Prom is on the Corral.

[@luisvelazquez3009]

It's more expensive than other systems, but a much better system, I desperately would like to get for my 88 notch, but just can't afford it

[@franciscosantiago8447]

If anyone is interested I’m selling my prom off my 86.
