Just replaced a bad computer in my 1990 F150. I would like to have the old one repaired and save for a spare. Who does that kind of repair? Thanks for your help.

 

I know my local tv repair shop owner pretty well, bring him a steady supply of little tv's/remotes etc to fix for our little motel here.

I needed a digital converter box looked at and had the PCM out of my 94 already so I brought it with me. Ask him if he'd replace the capacitors in it and if so how much.
He quoted "10 bucks plus parts", well when I picked it up it was 20 bucks.

I'll tell ya 20 bucks well spent, my truck has throttle response like you wouldn't believe now, just like it was few years back when I bought it (had 40K on it then).

It holds OD like it did when it was newer, not dropping out at slightest amount of throttle increase, it'll easily push itself up and over hills and hold OD doing it. Heck I can accelerate in OD and do so fairly quick, haven't really been able to do that in quite some time now.

It's like I put a fresh motor in it and that has to have had an effect on fuel economy but haven't driven it enough to know one way or the other yet. Not thinking it'll 20mpg now no but thinking see a solid 15 with it now maybe even little better? Won't know until couple tanks of fuel.

First time I was there at the tv shop with it, I asked him if he wanted me to get the capacitors or if he wanted to, he took the numbers off them stated he would.

On the way home I got to thinking and I called him up, told him to get enough to do the job twice.
I'm gonna take the PCM out of my 95 and drop it off next. Gotta say I have high hopes it will have the same effects with that one. 94 is a 5.8L, 95 is a 7.5L, both where getting around 10mpg and feeling confident having those replaced will give em both a boost in that area too.

If not don't really care, if its 10mpg its 10mpg but its not so hard to take paying for the power when you're actually getting it!

 

I saw your question about getting your spare ecu repaired. I actually have been doing ecu repairs for the last ten years. That is one of the easier ones to fix. I have the equipment to simulate all the sensors, inputs, and load the module down. I work on all modules in the vehicle. Be careful buying new modules, that can be expensive and risky. I would always attempt to have an original module rebuilt. My company is called Ecu Repair Now. You can reach me at 618-303-6957. I also do my best to help find what caused the module to be defective, in your case that would not be necessary because most of those types had leaky capacitors. I would give you my website address, but I do not want to get in trouble, I love automotive forums!

 

Excellent to see someone, especially a fellow Illini, repairing these PCMs. I did a simple search to find your website. I will bookmark it for future reference.

 

It shouldn't have to be a secret... ECU REPAIR NOW

 

I'm also guessing you would be the man to repair the notorious PSOM or even wiper control module issues?

If yes on the PSOM, then how would one ship one to you being that they should be kept at a certain orientation?

 

The PSOM is an electronic circuit with components on it, there is no need to keep it oriented in an upright position like the speed/odometer. If you need your PSOM repaired remove it from the instrument cluster before shipping it.

Good to know! Hopefully others' will find this thread when having problems with their speedometer or odometer and PSOM.

 

I am in South Florida until the first week of November. I've been down here working with my engineer friend on a few things we have had some problems with. He's a brain! He is more into software and I help with hardware. I am always willing to look at and test any module in the vehicle. If it is something I haven't seen many times, I'll test it for free. I don't like the fact that companies out there (especially the two I worked for) lie and promise everything under the sun. The truth is some modules can be tested accurately and not all modules can be fixed! But, then again I am not a salesman, just a tech. The PSOMs orientation won't matter during shipping, just make sure it is wrapped up so it doesn't get damaged by our wonderful shipping companies. I will need to know the exact problem you are having with it, the PSOM or the wiper module. I'll take a look at it and we'll go from there. If it tests good or if it is not rebuildable due to damage and you would like a replacement I have resources for that. Also I need the year, make, model, and engine size. I normally use UPS ground.

Hey Jbradley, do you still rebuild these EEC units? I have one out of a 1991 F-150 I may need rebuilt (again). Thanks to RLA (another guy who has posted on this thread) I think we have identified that the computer needs to be rebuilt. It has been rebuilt by cardone, but appears that may not have done the trick. Anyways, please let me know if you still do this. My email is skoglunc@gmail.com. or if you would rather call, let me know and i'll PM you my phone number. Thank you!

 

Have you opened it up to see what's wrong? I would hope that Cardone would have replaced all the capacitors, but that may be optimistic thinking on my part.

Alternatively, doesn't the part have a lifetime warranty?

 

Jbradley has not been on site since 2012.

 

I watched several you tubes where they replaced obviously leaking capacitors. All the systems had 3 capacitors- mine only has two.They dont seem to be leaking- and everything looks very clean.Should I just assume the capacitors are bad? Is there a place I can get a chart to run simple circuit tests on? I dont have those scanner things. Truck doesnt run. Quit suddenly. very good condition vehicle.
will someone test for me without trying to rip me off? John johnrflame09@yahoo.com

 

this was quite a few years ago now but from what I recall, these ECUs are almost impossible to test without the proper equipment. It can test fine with a volt meter but fail when in the vehicle. Even the rebuilder can miss something bad. I had to send my rebuilt ECU back 3 times before they got everything.
