I have a 94 Mustang Road Course Mustang with a Cobra 302. I'm getting ready to put in an E303 Cam. I've been running the stock T4MO computer, and it runs rich at idle all the time (barely idles), and takes about 48 PSI with 24 lb injectors to run at around 13:1 at full throttle - that's with the original cam.
I will be taking my car to the shop for dyno tuning when I'm done. The dyno shop suggested that if I run the stock T4MO computer, it is actually a better computer, but not nearly as programmable as the A9L. He said I may need a chip for the T4MO, which is illegal in the series I race in. Thus, I may be wanting to swap to the A9L, which should not require a chip.
First, I would welcome any additional information on the ins and outs of why to stay with the T4MO or go with the A9L.
Second, he said it would cost about $500 for him to swap the computers (above and beyone the cost of dyno tuning). My understanding is that all you have to do to swap the computers is swap a few wires on the ECM harness. I don't have to worry about the electric fan controls which I understand would normally be an issue as well, since I've already installed a separate fan control system - and then took the fan out completely anyway.
I would appreciate any information on the wires that need to be swapped, and any reason why the install would be complex enough to warrant $500 to make the swap.
I'm exceptionally good with electrics. However, I have to have the information on what I'm working with in a case like this. Swapping wires is baby stuff. Heck, I just got done removing bout 3/4 of the wires in my car, and looking for more wires I can remove, and everything still works right. In other words, don't be concerned that you will be over my head. As long as you say things in a way I can understand it, I can figure it out.
