g60bv 0 Posted February 18, 2004 hi i need help, i'm getting my 'c' mapped soon by a local guy, not a vw specialist,.. i know i know but i cant find any one local-ish who could do the job, i live in redhill, surrey. i used to travel to jabba sport each time but two tanks of petrol and and whole load of cash., :shock: any way my question is this... what should the fuel ratio be through out the rev range under load half load etc. one guy said 10:1 which sounded ridiculously to high. i understand the perfect mix is some thing like 14.5:1 plus this will be taken from the exhaust. when it was rolled last time my low range was 9:1 to 11:1 and my high rev range was 16:1, bit weak, i've got water injection to hopefully prevent any damage and i'm not racing until this is sorted, . i can even set fire to the exhaust, at idle.. it goes in next thursday. any help would be great. current mods big v ported head 35mm ex piper 270 cam grey injectors st4 charger single entery charger 65mm pully custom c'cooler water injection and some other bits and bobs boost 16-17psi 6200rpm had made 230bhp/280nm at jabbas on 68mm and crap charge cooler last year. :lol: ***mod edit - Please turn your CAPS lock off! - Henny*** Quote Share this post Link to post Share on other sites

Dubcharged 0 Posted February 20, 2004 Optimium a/f ratio on a force induced car should be 11.5-12.5:1 under WOT, 14.7:1 is in closed loop, ie off full/partial throttle. Darren should be ble to sort you out with a suitable SNS map. Darren: Do a wideband just in case the injectors cant cope. Quote Share this post Link to post Share on other sites
