Hey guys. I got a cherry condition 2001 302 from an explorer that was babied. I need your expertise to help me get this running with an A9L without anyy issues.
I have an A9L I want to run with this so it is a stand alone engine from the vehicle. Already have the correct harness. I am trying to figure out what I need to do to revert this 01' 302 to run with the A9L without tuning it. Trying to get it running as well as possible without a tune. This vehicle is a toy. I have 19# injectors, Explorer cobra intake, GT40p heads, BBK shorty headers, and am welding a flowmaster Hpipe exhaust. Reverting it to a distributor, and I am keeping the EGR for lower head temps. This is all getting dropped in a Jeep, but is a swap I know a lot of Mustang guys do putting an 01 in with their A9L. This is the forum I have been browsing and finding the most for info for this swap, so I figured I would post here.
I picked this motor specifically because of its truck cam, heads, and awesome condition. Low end torque is what Im after, not high revs. I do not want to have to have this A9L tuned unless I have no choice. Even if that means running lower performance parts. Reason being, even this motor toned down will beat the hell out of the 4.0 6cyl for turque, and future upgrade options. I can slowly start upgrading stuff with other parts I have later on one by one to see what may cause issues once I have this running solid., but to start, I just want it running and reliable. Not rich, or lean, I would like to get it just right. I am guessing I will have to use a Mustang MAF, or can I put the mustang sensor in the larger explorer MAF housing? I am converting it to a distributor as well. Wasnt sure about throttle body, TB senors like IAC and TPS working with the larger throttle body if I just stick ones from a mustang in the larger housing. Fan I am going mechanical because mud/water submersion has killed every electric fan I ever put in a Jeep very very fast.
Another thing throwing a monkey wrench in all this is that I have the entire ford fuel injection website ripped to PDF files. I know what pin outs are on all the different sensors and things, but it does not specify anything about using OBD2 sensors, with only the EEC IV pins hooked up. It seems on most OBD2 sensors, they have the same exact stuff as earlier sensors, with some extra pins for extra info for OBD2. Because I have every pin out digram, I was not sure if I could use existing sensors when I wire up my harness from scratch and just ignore the pins that have OBD2 info the A9L doesnt need..
This is all going into a 95 Jeep YJ with a Dana 44 front axle from a Classic Bronco, Explorer 8.8 rear (hoping to use the VSS output on that 8.8 for my EEC since I have a stick) NP435 trans, NP205 Tranfer Case cable speedo is going to dash gauge, and thats pretty much it. Meat and potatoes hookup I hope to make as reliable as possible since I put this Jeep through hell and is the third time I am building it, first time with 302 though. I was not sure if the earlier mustang 8.8's with an A9L used the same carrier sensor for the VSS I could drop in this late model version with the disk brakes, or if I should just try to wire the VSS output to the A9L using only the VSS output from the differential that is for OBD2, and ignoring the ABS pins.
I know this all might sound over complicated, but the most info I found on this setup has been browsing this forum. I am really hoping you guys will ignore the fact I have a Jeep, and just focus on helping me getting this motor to run completely separate from the rest of the Jeep. It may be easy, may be a challenge to figure it out. I assume if I use the stock foxbody MAF with my cobra intake I will not need a tune, but will be restricting the airflow which is why I wasnt sure if I put the sensor in the larger housing if it would work or not since it would think it is in the smaller housing.
Some engines in the past I have been able to change things like throttle bodies, injectors, and just gained the extra power without a tune. Those were also EEC IV. I do NOT want to go OBD2 on this. I would if I could drop $1k on a custom unit I could tune myself, but I dont have that cash to throw at this build right now with all the other stuff I've been buying. Im actually an IT Tech, so wiring and things arent bad. Its really figuring out what to use on this block since it is still on a stand. I do not want to drop it in, just to crank it and have it running like crap.
Thanks for any help you can offer. Sorry for the long post, but I have been spending a year aquiring parts, and am about to paint the block, and swap whatever sensors I need to revert this back to a foxbody motor.
