So I think I have had a win and nailed the cars issue with the missfire.. Intank fuel pump seems of of been sh*tty.. I guess that checks out as when my old car (with the same intank pump, but different surge) was tuned by a Adelaide workshop it started to lean out uptop on 98 then it cleared its throat came good and never nailed why it had a lean out on 98.. Then when Bluepower tuned it on e85 they ran into a lean issue where it should of been fine still (at 413rwk) and they tried a couple of sets of injectors and a different surge tank setup (I run a plazzy setup with a peirburg pump - they tried with 044 pumps).. Anyway overtime the car got hard to start and I though the surge pump was rooted after 12,000kms by passed it and ran it off just the intank and it started like it should.. then it started and would miss after 10 seconds, tried a mates fuel pump assembly and whalla was all good again.. So who knows maybe the issues both tuners had was the intank pump was struggling to keep up with the surge? I dunno I'm no tuner.. Anyways So I replaced the intank which was a walbro 255lph pump with a walbro 250lpg as they are apparently e85 compatible and the 255 isnt? Only issue I noted when I ran the car off just the 250 was it was hard to start; had a 4ish second crank time but then I read that the 250 doesn't have a check valve to that explains why there.. Hooked the surge back up and it seems to be starting and behaving like it should of the whole time..

Anyways never actually posted good pics of the car, so here goes - finally clean and ready to be registered after being off the road since mid november 2020. Pretty keen to put some kms on her and get it in the shop for a retune, thinking of going PCMTEC and making the best of what it has, as I already have a innovate motorsport ECB-1 gauge which can be used with PCMTEC for E85%... Currently its a dinosaur and still xcal3 tuned!
