  1. Hotlap....Thanks for your input and encouragement. I don't have a wideband..it would be a useful addition though. Dose Pipe...Thanks for your dis-couragement I'll get it sorted one way or another and will post an update when I do, as I hate threads that die without ever getting to the resolution.

  3. Sorry Hotlap I haven't checked here for awhile. I have not tried to drive the car since I swapped from the MT-8 to the LT-8 as it won't idle and when accelerator is pressed it just starts spluttering. I'm also hearing a rattling noise which has really got me concerned that all this playing with settings has done some internal damage. At this stage I might wire the MT-8 back up and check if it still runs fine with it before I go any further. Unfortunately for me I have an early MT-8 with a single plug and the LT-8 has 3 plugs so swapping back means I have to un-pin and re-pin all the molex connectors...which is a pain in the butt.
  4. OK I am getting more confused by the minute. Below are the settings I found on the LT-8 when I got it: T_gap >500 = 15deg 1000 = 15deg 1500 = 15deg 2000 = 14deg 2500 = 12deg 3000 up to 9000 = 10deg T_inj >500 up to 4500 rpm = 180deg 5000 up to 9000 rpm = 210deg So sorta looks similar to yours Hotlap. The email I got back from Microtech said the base load program file is not in a format that they can easily check but just setting them to zero should be ok. I think I've tried both now and still not running as it did with the MT-8. I've rekeyed all the maps from the mt-8 into the LT-8 only to discover that when I set the STATIC timing value to 10deg it automatically bumps up the timing values in the T_rpm fields and won't let you set them below the static value. On the MT-8 I had values of 9deg, 5deg, 6deg, 9deg in the first four fields of the T_rpm and a STATIC timing value of 10deg....but I can't seem to match this on the LT-8 no matter what I try to fool it. Maybe it can only be set like this with a Microtech factory base load file? I think I'm finally at the stage where I will need to send the ECU to Microtech and have then reload the base load files.
  5. Thanks Hotlap. I'll keep checking in for your update. I have also written to Microtech, but no response yet.
  6. Not that easy for me to use a stock ECU with Nistune. Motor is actually in a Datsun 1200 ute and I have deleted a number of things in the process.
  7. Anybody? Was hoping to have an answer this weekend so I could give it a try.
  8. Thanks Hotlap. Keen to see what yours are set to! I have to say that after waiting a few days for a response and also writing to Microtech Support with no response I did set all the T_gap settings to zero and it ran a little better. But I have left the T_inj settings as I found them which are at 180deg from 500-4500rpm then 210deg from 5000-9000rpm.
  9. Microtech LT8 on CA18DET - t_gap?

    Protius..I bought the LT8 secondhand from a guy that was running a CA18DET in his Holden Gemini. So should be OK. Wizard.. you are pretty much on the money with what the T_Gap settings do..They allow you to alter the timing gap between firing the leading and trailing coils as the revs change . and the T_Inj function allows you to set a delay time before the injectors are fired allowing you to fine tune the precise timing of the injectors as the revs change. I'd just like to confirm if for non Rotaries the T_Gap settings should all be set to 0 (zero) and same with the T_Inj.
  10. Yes probably a bad choice from the start. There after sales service leaves a lot to be desired. The standard response they give to any issue I've had with their older ECU's is "why don't you buy one of our newer models". Anyway I'm in to deep now and know that I can get it running ok once I correct some setting....surely there must be someone else on this forum still running one on a CA or even an SR that could quickly check there settings??
  11. The MT-8 had a fault and Microtech don't repair them anymore. I didn't want to rewire the car so easiest option was to buy another Microtech. If I did it again I would probably go Haltech.
  12. I have recently swapped from an MT8 Microtech to an LT8 model and am having problems getting it to run properly. I copied all the data (load/ignition maps etc.) from my MT8 and entered them into the LT8. However, the LT8 has a number of additional screens. The ones I am trying to find out about are the T_gap and T_inj screens. Can anyone with a similar model on a CA18DET tell me what settings they have. According to the User Manual the T_gap is for Mazda rotary's only. But I have settings in there and want to confirm if I should blank them out (set to 0)? Same with the T_inj screens. Any help gladly accepted.

    I have now copied this across to the Nissan Silvia Tech Forum as may be more relevant there.
