S40 Twin injector troubles

Post by Ade »

Hi I'm using an S40 pro with supplied firmware 79.00 , my bike runs eight injector bodies. The problem I'm having is once I tick the twin injector box the secondaries run with the primaries even on cranking even though I set them to activate above 5000 rpm and 23℅ throttle!! Both sets sets of four are wired in parallel ,primary's on injector 1 and secondaries on inj 2 they are both approx 12ohm impedance so a 3ohm total load on each injector driver ( works perfectly on just 4 primary injectors ) yes the wiring is fine , so do I have a hardware,firmware, or software issue ?? Any one else had problems ? I see a map file for a gsxr1000 k5:/k6 mapped by dta that uses the same setup with twin injector box ticked

How's that going to help ? I've given plenty of info' like I said the secondries shouldn't be triggered until above 5500rpm and 23% throttle let alone drowning the motor on cranking

Exactly, 30 minutes or hours spent pissing about with incomplete information, bits and pieces, looking at screenshots could all be resolved in a few seconds with all the relevant info. ie the map.

Your map "may" be all correct....but until we can see it, there is no way of confirming. And taking someone elses word that it is correct.....but there are problems, is going around in circles.

it may just be that they havent spotted where it is incorrect.
