1991 F150 XLT Lariot ecm swap?

Unread postby dnalley8 » Wed Mar 04, 2020 9:26 am

Hello,
I am very new to tuning. I own a 1991 F150 XLT Lariot with 5.8L and E4OD transmission

I want to tune my truck for torque, idle, fuel economy, etc. I have an EEC IV with the following:

C1Z
EFI-SD47B

I have plans to buy a QH and BE

Can I tune this ecm or would I be able to or have to swap in one of the early Lightning C3P2 or C3P3?

What is the best/easiest way to tune my truck?

everything's tune-able just depends on how much you want to spend to get the support.

I take it your trucks all stock/original?

You can use the quarterhorse and download tunerpro and the sd-4x def from the homepage and give it a go first if you'd like.

Engine rebuild is pending. new heads, cam, headers. I will get the quarterhorse and tunerpro and give it a go. Check back in a month or two. Thanks for the response.

I am still curious, can the Lightning ecm be swapped into my truck? They are both similarly equipped.
