Which PIMP should I get X or XS??

[hrace18]

I have an 89 F250 with the 5.8 and 5 speed. The motor is fairly worn out and in need of a rebuild. I found the PIMP products while searching for a stand alone ECU for Ford's. From what I read the trucks are actually batch fire from the factory? I need a wiring harness anyways so would there be any benefit to getting the PIMPXS over the PIMPX? Also would I need to change injector style if I got the XS? Sorry for the questions, but until a few weeks ago I didn't know your products existed.

If you want to stay batch fire then you need the PiMPx and the batch fire PiMP harness (if not using the stock harness).

If you want to convert to sequential then you'd use the PiMPxs and the sequential PiMP harness. Whether you should go sequential depends on your goals. If you have plans to make big power (north of 500 or so for a V8) or run large injectors then sequential would be beneficial. If it's staying mostly stock with injectors around stock size then you'll likely not notice a difference.

Stock injectors work fine. Any high impedance injector works, though some injectors are better quality than others and therefore work better.

Note all of the ECU's require a wideband o2 controller setup. We offer the Spartan 2 w/sensor (gauge optional) to fill this need.

Thanks for the reply. No high performance build on this one lol. It's just a work horse tow vehicle/high school commuter for my sons, got to make sure they can drive a stick. I just noticed some redneck repairs to some wiring and since it's really in need of a refresh I figured a better than stock cam for towing a mileage would help it out. I was really looking to find out if the sequential would have better driveability characteristics, better mileage, etc. over the batch fire setup. I really appreciate the information!

Sequential will offer a bit better throttle response and can do a little better MPG but we're talking a few percent, not huge improvements.
