ECU doesn't match chassis

[JLP]

Thanks Fix!

Roger that on the 80 being unsafe. Guess I should have said it CAN do 80, think I maxed out around 70 indicated with room to grow one time. The point was that it's not limited to 2500 RPM or maxing out at 35 MPH. It runs good minus the fuel burn and smelly exhaust. So this sounds like Limp Home to you? What about Back Up? From what I've read I would expect the car to be barely driveable and chugging black smoke in Back Up mode.

Four times a day I drive a 1.4 mile route maxing out at about 50 MPH with one stop sign halfway through the drive. I'm in 5th gear by 35 MPH. Not ideal for USA MPG but it shouldn't drink like a big block.

Sounds like the incorrect ECU may not be ideal but probably won't hold the injectors wide open because it's in the wrong chassis. I will correct the other issues, change the CEL bulb, and check codes.

Are there any known CATS that will bolt up to the aftermarket header?

I know that no gas is being stolen or leaking. I don't really track the mileage but I always reset the trip odo and I put about 9-10 gallons in every 125 miles or so. NOT GOOD! Not even close!

Thank you!
