July 1st 2008 (Canada Day ironically)** only thing is I'm having issues with it backfiring, not wanting to rev past 2500-3000rpm when using light (14-25% TPS indicated) throttle. If you stab or even just depress the throttle 100% it revs just fine... I'm not quite sure it's accel enrichment related either and something to to with the TPS?? anyone have any ideas? * See IssueReports on what you need to publish (which is absolutely necessary for any investigation or further progress) ** mcd / mct dump (NOT msq) ** firmware version ** Datalog, datalog and then datalog some more.
