A couple years ago,I had a problem with one of the two computers for my '81 308. These are the ones that control the cylinder banks,located in the Drivers side rear of the car. My car started "Backfiring" occassionally,and running rough. Also,the Cats were getting overheated due to too much unburned fuel getting in them. I parked the car,right away until it could be towed in for service. Luckily,I had it repaired immediately,and there was no damage to the Cats or anything else. But,now I have 2 computer "Brains" One of which is still good,(I replaced both of them) and the other needs work. Is there anywhere that I can have these "Overhauled",and possibly,"tweaked" to enhance performance? I once saw an ad,I believe it was in either my Pilota ,or Prancing Horse. For someplace in England(?) that Modified the computers in 348 and newer cars. But,not 308's. So,does anyone know of anywhere that can do this to these? Or,anywhere that rebuilds them? They were about $1500.00 each,so,worth getting fixed,I think...? To either keep as spares. Or,performance enhanced. Or,? Thanks in advance for any help!!
