binny Posted June 23, 2020 Report Share Posted June 23, 2020 Hi Forum dudes, I've recently increased my 98 WRX's engine capacity from the stock 2.0 L up to 2.5 L - now I'm attempting to get a start out of it Symptoms: on switching on ignition fuel pump primes - 1st crank attempt will not fire, 2nd crank attempt engine fires but immediately stalls - this continues over and over note: ** no intercooler or intake piping fitted ** MAP tune / no AFM The car was running the ViPec V44 and Subaru's blue injector (650CC IIRC) with a fairly crappy tune (by me) - with a top mount intercooler, STi VF37 twin scroll turbo (bigger compressor wheel fitted - by Ray Hall) and aftermarket exhaust - seen running below I've seen I should be adjusting the master fuel table for the increase in displacement - Do I need to also adjust the Crank enrichment, Hold, Post start enrichment, Decay tables??? or should that be it? (or anything else I've missed???) as I can't seem to get a start and run at the moment! (old fuel???) Any help greatly appreciated I forgot to mention - I have a Innovate Wideband fitted AFR's seem very lean during cranking but possibly due to engine not running (as widen is using crank battery power) Quote Link to comment Share on other sites More sharing options...
