I have some ecu's in my garage that Im gonna swap in and out tomorrow and see if I can feel any changes as to power, fuel economy, idle, redline and rev limits. My car has a d16y7 which should be more economical than 20 mpg and a rev limit at 6200. I have a PG7, PM6, PO4, and Pr4 all obd-0. My question is does anyone have any experience with these ecu's and which delivers more economy or power?

 

I'll take your PG7 off your hands I live local to you. And I need one to get my 1st gen teg runnin.

On topic: What ECU are you currently running? I've noticed my PM6 ecu makes my car feel stronger mid-range than a PO4 and PR4.

 

i havent checked yet but i know its not stock. its supposed to hit rev limiter at 7k but hits it at 6200 in my car. Im gonna do some testing here soon.

off topic: Dude i got a whole dohc zc in my garage begging to be put back together. has everything minus pistons and rods and distributor. it has zc stamped right on the block.
