Max hayman Posted October 24, 2017 Report Share Posted October 24, 2017 Hi all, Have had a few link ecu’s over the years, never had any issues with them Recently we have “inherited” a skyline (92/93) with a link plugin with a few startup issues. We have done the steps for the ECCS sync, both trigger one and two are coming up as yes, the opening is coming up as 24 degrees. We then set base timing to 15 deg, put a timing light on the high induction coil (near the igniter) to get our timing mark near 15 degrees on the harmonic balancer we end up with an offset of around 95. on startup the engine will not start, it only backfires out of the exhaust and occasionally from the intake. but when the offset is down in the 40’s the engine stumbles to start then dies, but our timing is way off the mark. We are using the standard rb20 with 440cc injectors map, engine is as follows Rb25 9.5-1 compression (Ross pistons and rods) standard crank 254 duration cams-221 @.50 (vct delete) Aeroflow rising rate, brushless fuel pump spitfire coil packs (running wasted spark) iridium plugs Garret 48/54. ICS-1 wideband any help would be appreciated! Our overall timing is setup from the factory marks and the adjustable cams are the same.

Simon Posted October 24, 2017 Report Share Posted October 24, 2017 Check the timing on a HT lead between the coil and the plug on number 1 cylinder. Using the timing loop always seems to give issues. I would expect the timing offset to need to be around -82 for a factory CAS in stock position. Quote Link to comment Share on other sites More sharing options...
Max hayman Posted October 24, 2017 Author Report Share Posted October 24, 2017 Cheers, ill give that a try, will be a few weeks before I can give it a go due to fifo work, any other ideas what It could be? Quote Link to comment Share on other sites More sharing options...
Max hayman Posted October 25, 2017 Author Report Share Posted October 25, 2017 i will also attach a log, The only changes are the narrow band is swapped out for the wideband IAT are turned off due to link displaying 100 Deg C figures and wiping out the timing also forgot to add, i believe it is running a 750-800 CC injector (unknown brand) Thanks Max rb non start.llg Quote Link to comment Share on other sites More sharing options...
Simon Posted October 25, 2017 Report Share Posted October 25, 2017 Can you flick up a copy of the map to match that log. Quote Link to comment Share on other sites More sharing options...
Max hayman Posted October 25, 2017 Author Report Share Posted October 25, 2017 Can do Simon, Just using the Standard Link Map, Only changes being IAT is off, and a wideband instead of the factory Narrow band. Appreciate it! Nissan Plugin G4 RB20DET 440 With wideband.pcl Quote Link to comment Share on other sites More sharing options...
