Got a good runner now, I'm not sure if it was due to the plugs (LINK recommended resistor type) or if it was due to my terrible and sloppy engine wiring harness.
Mike Rose came by yesterday and gave me hand with the harness, much easier with 2 people to route the wires thru the car. LINK ECU is now mounted inside the cabin...I removed I think 6 wires completly from the harness which I have no use for in my application, I also shortened the other wires by about 3 feet. Still figuering out the tuning thing....I think I might end up putting a TPS on it since the vac. only is a PITA at idle since my vac. signal seems to vary from 35kPa to 65kPa each time I release the throttle (1.7 intake system with stock throttle body) Car starts and idles fine, I tried to drive it up the street and it's too lean...not sure if it was during acceleration or just under load at that particlur MAP setting..... I'm a happy camper and I'll be even happier when I figure out how to tune the computer better (IMG:http://www.914world.com/bbs2/html/emoticons/MDB2.gif) |

heheh good for you Mike...
Some of those extra wires are like antenna they pick up stray electrical noise, and make havoc with the way the engine runs. A TPS will be beneficial, as in TPS mode the ECU uses MAP besides throttle position to adjust fuel Tune in the increments the table shows, the map I have for my car is based on 500 rpm intervals Hold the throttle at a given rpm and adjust fuel... if the indicated cell jumps around you can adjust cells of lower and higher manifold pressure also move to next RPM position, repeat when you have fuel adjusted to a safe ratiosn throughout your rpm ranges.. play with timning |
