Controlling the ECM

[cameraman7d]

I have a stroker which is running good on the stock ECM. I also have a unichip and software to custom program it... from all i am gathering the unichip only controls the signal to fuel and timing when the computer is in open loop during WOT... so i am interested in what ways i can control the fuel and timing during the rest of engine duty cycle...

can i trick the computer into open loop. thus allowing the unichip to be effective through out the rpm range...

are there other more effective engine management options...

how would a map adjuster work to help this problem???

I have an LM-2 and watch the AFR which is constant at 14.7+/- and at WOT its between 12.8 - 13.2

i would just like to see more power outta this motor at cruising speeds i.e. climbing a hill on the interstate..(i have stock tires free flowing exhaust, and intake 24lb injectors and 255gpm fuel pump rail psi @ 49.)

any suggestions are welcomed Thanks, AC

Looks like your fuelling is bang on the mark, so the only thing I can suggest is to slot the bolt holes in the CPS and move the sensor towards the centerline of the Jeep to add a bit of timing advance. You'll need to watch for pinging though especially when climbing hills.
What are the specs of your stroker and what ratio axle gears do you have?

If you're willing to ditch the Unichip, I can help, add additional features to the stock calibration and still retain closed loop. I can refer you to others that can vouch by my work.

I´m actually interested in what you can do, Ryan. Right now I´m running an S-AFC that I rigged up to work. Had to use an MSD DisTach driver to get the RPM signal massaged to feed to the piggyback, but it lets me control the a/f adjustment maps. No control over timing, however. What do you offer and what can I expect from it? PM me if you want to discuss offline.

Ryan knows his stuff that I can vouch for.
