i need a reprogrammer for my 95 cougar 4.6 dohc. i asked a friend of mine if he knows anybody with one for a mustang and he told me it wouldn't work cuz it would probably be a different fuel computer. so the question is, what cars IS it compatible with? obviously i'm hoping to get lucky and find a friend with a compatible reprogrammer.
I have no idea,but,I do wonder how close it would be to the 4.6 pickup programming.
Explain why. What are you trying to accomplish?
Won't be what he needs he has switched to DOHC If I'm reading that right. You swapped the motor? Or just got the terms wrong?
If it IS a DOHC,then maybe a Mark VIII.
It is possible to do the swap and keep the existing SOHC harness and electronics. It's a nightmare to swap that stuff. Perhaps this is why you need the reprogrammer, Billboehm?
i tell you to look into a programmer for a mustang corba one. they came with the DOHC so did the lincoln mark's like vinnie said. other than that if you are handy with a soldering iron/gun then you may look into these guys. http://www.moates.net/documentation.php?documentation_id=72
most of it is build your own but i think you can buy them pre assembled units also.
If he kept the wiring and ECU from his 2v how would a programmer for a 4v motor help? Totally different system. We need more info....
sorry i typed that in wrong. it's an SOHC. sorry for the confusion. as far as what i want to accomplish is reprogram my throttle curve, shift points, and to tell my motor to accept more air.
The parts combo and valve timing you have has more of an impact over that than the ECU does. The ECU can optimize it to work to it's fullest potential provided you have it calibrated correctly;)
I would call SCT or an authorized dealer like 5.8fastcat who posts here. You can PM him or visit his site. I'm sure he'd be more than willing to help. His website is: http://www.speedydyno.com
As far as taking in more air, have you considered a PI swap?
pi swap, easier said than done. can't seem to find any mustangs at junkyards here. but that was referring to the fact that my thrown codes may be due to the k&n filter i got on. autozone says both banks are running lean, which means too much air for the programmed perameters right?
A simple K&N shouldn't throw a code on the EEC-V equipped cars. Did you hook the Egr tube up to it? Sounds like maybe you have a leak somewhere. Also how old/new are the o2 sensors?
Also, check your PVC system, if there is a leak, it is after the MAF which lets the engine have unmetered air, and throws lean codes, they are bad about the soft rubber tubes rotting and getting holes in them. You just have to follow the lines, your car has the funky rear entry TB, and one of the lines goes through there. You can check for leaks by spraying the PCV lines with brake cleaner, if there are leaks, the RPMs will change.
no idea how old the sensors are and ya i think i do have a leak. but the light's on since before i added the k&n. i'll fix the leaks first and if that doesn't work then i'll replace sensors.
Like they said. A vac leak will cause the car to run "LEAN"
and that will cause a check engine light
ok i fixed leaks but haven't started it yet. gonna check that on my way to work tomorrow. if the problem is my maf sensor, will the sensor (just the sensor not the tube too) i just pulled from my 93 3.8 work for my 95 4.6?
How do you know they are fixed if you haven't properly checked yet?
As far as the MAF question:
http://www.graphicsdept.com/walbro/product/auto_aft/mass/forda.htm
The electronics have a different part #
You could try it, don't know how different it is though....The '95 is EEC-V. Is the '93 3.8 EEC-IV or EEC-V?
well i knew where the leaks were. couplers weren't hooked up right. and how do i find out if it'sa IV or V?
The '95s are EEC-V
What you need to do is REPAIR the problem, the last thing you need is a reprogrammer... A dirty MAF meter will give lean codes...
The chart Paul posted indicates the 3.8 & 4.6 Tbird meters are the same for '94 & 95... I know the '96 & '97 have a different connector shape so won't fit, otherwise the meters look the same... Those may would work if the connector plug were changed to the newer type...
When the meter on my 95 4.6 T-bird failed, I tried a 5.0 meter and it ran like shiznit in cold weather... Also set a rich code the day after I installed it(weather was still warm)... Replacing it with the correct one from a '94 3.8 cured the problem...
but it's not a 94 that i would be getting it from. it's a 93 with a 3.8. will it still work right on my 4.6? the connector is right, the question is programming (if the programming is in the sensor).
Don't have a clue, it's not the same by the chart...
Have you tried cleaning the current sensor????
If the '93 3.8 ECU is an EEC-IV I would think you may have issues. From what I understand the 3.8 was EEC-IV until '96.
Your MAF list shows the '94 & '95 3.8(EEC IV? Hell I dunno) being the same as the 4.6s... I can confirm the '94 3.8 meter has the same part number on the sensor as the '95 4.6... Were the '94 4.6 Birds/Coug VI or V???
I know it's weird....Perhaps the IV and V were designed to use the same meter. I'm not sure.
well it looks like the same meter from the top. i just hsven't gotten around to taking it off and looking at the bottom. but my primary question is weather or not the meter itself is programmed or if it just sends raw data to the computer.
k so i swapped the sensor the other day while i was waiting for my boss to unlock the office so i could drop off the tools from a house we just finished. my check engine light is still on so i guess that wasn't the problem, but here's the wierd part. apparently the sensor is in fact programmed for the motor instead of just sending raw data to the computer and letting it decide. the sensor came from a 93 v6 and went into my 95 v8. so the stats on the maf should be for less gas right? well i have no idea how, but it gave me better acceleration and better power through the midrange! somebody explain this please!
Were the part #'s on the electronic part of the sensors the same?
The sensor does not know how large a motor is or how many cylinders it has or what size injectors the motor has. Tha't info that the computer knows. The meter is designed to measure airflow through a tube of "known" diameter and send a signal to the computer. There are ways you can change what signal the computer recieves and interprets. A change in the sampling tube size is one.
IF it's EEC-V, just fixing the problem won't turn the light off... Will usually go out in a day or two though... I believe V was required as of '95...
