tortron Posted December 3, 2020 Share Posted December 3, 2020 about 2000 rpm is where the ecu will reset itself (tps etc) when the ecu has been unplugged, and then starts relearning on the next start up. Perhaps you have a wiring issue where the ecu is losing its memory/power overnight Quote Link to comment Share on other sites More sharing options...

Muncie Posted December 4, 2020 Author Share Posted December 4, 2020 @tortronIm going to put my multi meter on the DFI power i wonder if ive got a voltage drop causing it to brownout and partially shut down causing weak spark as it stinks of fuel when it runs shit.

Muncie Posted December 5, 2020 Author Share Posted December 5, 2020 @vk327 would you say this is an accurate accurate pinout for a vy? Multi meter says otherwise, best voltage i got from 2nd pin from left was 10.7 volts. Quote Link to comment Share on other sites More sharing options...
vk327 Posted December 6, 2020 Share Posted December 6, 2020 yep that diagram is correct, should be gettting 12v on pin P when ignition is on, check what the voltage is at your injectors too could have a high resistance relay or fuse feeding that circuit Quote Link to comment Share on other sites More sharing options...

Muncie Posted January 7, 2021 Author Share Posted January 7, 2021 Another new crank angle sensor has resolved the issues i was having. Have flashed an Enhanced bin file into the Ecu, this is essentially a firmware update and makes changes a bit easier to make, nerve Racking though as flashing a Bin file is considered risky and can brick the ECU. It failed first attempt then sat with "No response from Ecu" message coming up for ages in OSE flash tool. It then came back to life and successfully loaded second time round. The new enhanced bin i got from the pcmhacking.net has some goodies that add a bit of extra ignition timing and line pressure to trans. Its a starting point and from here onwards i only flash in tune portions of the bin file. Its dead easy to do i just need some practice working in tunerpro making changes. If anyone knows their way round tunerpro please chime in. Quote Link to comment Share on other sites More sharing options...
Muncie Posted August 27, 2023 Author Share Posted August 27, 2023 Can anyone help with this? I can not get Tunerpro up and running to see live data. Osm flash tool connects and works so it's just got to be something really small but im out of ideas. Quote Link to comment Share on other sites More sharing options...
drftnmaz Posted August 27, 2023 Share Posted August 27, 2023 Probably no help but ~14years ago when i messed with Delco tuning stuff I remember being stuck and couldn't get the live tuning bit working. Turned out I had to load 2 different files into the program before it would work, was a very simple thing that took me ages before someone pointed it out, (like a Bin file and a xps file or somthing) because everyone else did this without thinking about it so it wasn't ever mentioned, lol. Unfortunately this was so long ago i can't remember the excat details sorry Quote Link to comment Share on other sites More sharing options...

Muncie Posted August 1 Author Share Posted August 1 I'm still mucking around with tunerpro and Delco buggery with some reasonable success but still some problems. If anyone has or knows their way around this stuff I'd like to bounce ideas around. 1 Quote Link to comment Share on other sites More sharing options...
Muncie Posted September 28 Author Share Posted September 28 At this point of the project I'm both open to help from others but can get around a Reflash pretty effectively. I've got a repository of good tunes both N/A and Turbo if anyone wants some basic stuff done like VATS switched off etc hit me up here. 2 Quote Link to comment Share on other sites More sharing options...
