Fitted my 46mm bike bodies some days ago. Have until now run on 42mm bike bodies with a ecu mapped for those. When l fitted the 46mm ones the engine runs like s**t. The map is the same, but l didnt think it would be that off with a bit bigger throttles. The car wont rev when driving, when l foot the pedal it only comes alot of noise ,but it wont pull.Help,help |

What everyone else said, what did you expect? It'll be miles out at low throttle openings. You're lucky it hasn't gone bang if you've loaded it up like that.________________________________________ - Bespoke rollcages/additions/adjustments.

When I had jeneveys I had a base map on the ecu and it was no were near drivable and if its overfilling it will bog down and you'll wash the bores. I know your ain't a base map but it will react in the same sort of way. ________________________________________ 98 onyx black 306 Rallye53 Nissan Primastar silver (work horse) 58 black Volvo c30 sport |

Probs worth getting that sorted first then get it mapped, save doing it twice. ________________________________________ 98 onyx black 306 Rallye53 Nissan Primastar silver (work horse) 58 black Volvo c30 sport |
