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 |

Hey Tim,
Yep, that is pretty much how I was tuning it...problem I am now having is that I cannot seem to get enough fuel during acceleration, I've played with the "accel" inputs and they are not doing it for me. I'll e-mail LINK and hopefully they'll be able to tell me what I am doing wrong. I switched the setting from VACUUM to MAP and then to MAP+TPS (with no TPS) and it actually ran best at MAP+TPS (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) ..the accel is still wackey, but no big deal right now. Now that I got this far, I'll pull off the throttle body and install a new TPS onto it, I'll be needing the TPS for sure with my next intake setup so I might as well learn how to tune it. Andrew, if I'm back from Louisiana in time I'll try to make the V8 meet. |

Don't worry about acceleration and accelerator pump issues right now. Just get the cells right. No sense working the accel pump if the main map is wrong. It'll just make it harder to set the main map. In fact, you might think about zeroing the accel pump setting so that they don't screw with you setting up the main map.

I'm planning on coming tomorrow or tuesday night for a burger and get the LM-1. Any conflict for you? |

I don't know how the Link works but on my SDS accel pump works off of the TPS.
Glad to hear your making progress. (IMG:http://www.914world.com/bbs2/html/emoticons/cool_shades.gif) |

aaron should be happy...no camera phone pictures here (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)
LINK ECU mounted inside...once the backpad is installed it'll be hidden (I shouldn't have to access it except for massive tuning changes once setup, so no big deal if hidden away) Attached image(s) |

I had to use some resistors with the injectors due to the impedance of them (stock 2.0 injectors)
Sooner or later I'll re-do the wiring harness and use different connectors, these are GM Weaterpac connectors. Attached image(s) |

here is a shot of the wires removed from the harness that I did not need with this install along with the extra length of wire removed from the needed wires so that the harness was not too long.....

Does the LINK have an LED for error codes on the unit or does have a lead for a dash light or neither?

for error codes I'd have to plug in the laptop or the pendant (which I didn't buy)

Update on the Link...I got the ignition problem solved, it was due to not phasing the trigger and the rotor inside the distributor correctly...
been trying to tune it today with a little luck....cannot see my laptop screen due to the sun so I'm going to wait until tonight and drive around the neighborhood to tweak it better...... |
