Shane Deadman Posted July 19, 2014 Report Share Posted July 19, 2014 Hi all, I hope someone out there can help me. Im new to tuning a g4. I have a AU falcon xr8 220kw engine in my pickup truck with a g4 running it, the trouble im having is it starts sweet as when cold but drive a k down the road or just shift it out of the shed and try to start a little later and it cranks forever pops and bangs then eventually if the battery aint flat it starts,touching the throttle doesn't help, drive a 100ks and it starts a little better, has seemd to get worse recently (possibly the cold). Have tried increasing the crank enrichment and also decreasing neither seems to help. There is probably a 100 things I need to change but don't fully understand how to navigate the tuning programme. Have got so sick of it im considering going carby as I understand them.Please help Quote Link to comment Share on other sites More sharing options...
Dave Kriedeman Posted July 19, 2014 Report Share Posted July 19, 2014 Hi Shane, can you post your tune file. How cold is it where you live at present. Have you calibrated the ignition timing correctly etc. Has the ECU been tuned or is this the first start up etc. Regards Dave Quote Link to comment Share on other sites More sharing options...
Shane Deadman Posted July 19, 2014 Author Report Share Posted July 19, 2014 Hi Dave Thanks for the response. I should have added more info, Was dyno tuned several years ago but didn't have the IAC fitted so have since set that up (hopefully correctly) . Im in NZ , the IAT was 9deg when I played with the crank enrichment this morning. Its always been temperamental to start after first start. What I find is ill go to work in the morning starts mint its a 1min drive to work 4hrs later starts good to come home for lunch but a real shit to start an hr later to go back. I haven't done anything with timing as yet. It runs sweet when going although I have a AU 220 xr8 with similar cam specs but running standard ecu Afm and big bore and it seems to have more power than my pickup which is big bore no AFM and should in theory have a better tune. the xr8 is also more economical. the pickup although not aerodaynamic is lighter but gets about 300ks to 60ltr, so maybe beter tuning required, I should mention that its got a innovate wideband and generally runs at around 14.5 to 15.5 at cruise. Im real computer illiterate so not sure i know how to attach my tune sorry, but if anyone out there has a good tune for this combination id like to try it.

Dave Kriedeman Posted July 19, 2014 Report Share Posted July 19, 2014 Hi Shane, You need to find where the LINK file is saved to, I always save these types of files to my C DRIVE but it could be anywhere.

Shane Deadman Posted July 19, 2014 Author Report Share Posted July 19, 2014 Hi Am trying to attach my last road tune file from before I played with crank enrichment Quote Link to comment Share on other sites More sharing options...
Dave Kriedeman Posted July 19, 2014 Report Share Posted July 19, 2014 Hi Shane, Your PCL file you have uploaded is a PCL.TXT file, this can not be opened by the LINK software and there is no way of decoding the text file. You need to make sure the file is saved as a PCL file only. Regards Dave. Quote Link to comment Share on other sites More sharing options...
