looks like it is all good now. there was a miss on number 8, right in the roughest part of the cam. the leads were 3000km old and the plugs 1 tank of fuel, i replaced them and the miss has gone. Dave

Hi All, i have a monsoon GX4 fitted to a fast fuel 1000 TBI on a 10lt big block chev. Fitted with a MSD 6AL. up to 2000rpm it tunes well, ie, if the a/f is 14:1 and i move the fuel table from 20 to 30 the A/F moves to 13:1. the problem i am having is at 2000rpm there appears an invisible line that the engine wont rev past. some times the A/F goes to 16:1 so i add 30 points of fuel and it will show 13:1 and rev further then i let it back to idle, bring the revs up again to 2000 and it will show 11:1. once the engine gets passed 3000rpm all appears well. the A/f is measured 150mm from the collector with the dyno O2 screwed directly into the pipe. all fuel enrichments are turned off the ign is not controlled by the GX4 and a timing light verifies the the advance and no misses on the balancer. i have tried to find out the cam specs but to no avail,i am suspicious of a vacuum leak but dont know what manifold pressure this engine should have and it is a major job to pull the manifold in frame to check the gaskets. when the engine had a 950cfm carbie it would come off the cam at around 2000 rpm and smooth out nicely. any ideas would be apreciated.

I have a 320.028 vdo oil temp sensor, it is on GP temp 1 input, it needs to read from 0 deg C to 120 Deg C, it will be used to limit the engine out put or give warning if the trans is to cold or hot. I am looking for a table for a 1k pullup to suit. vdo oil temp sensor.pdf

Thanks I will look at it later. I would run a 0-5v sensor except for space limitation on motor bikes. I found the G4+ easier but it will be just a case of familiarity. One other thing... i notice the cal table wont accept numbers greater than 1500 is there a way around this?

Hi, I am trying to install a trans Temp sensor on a monsoon G4X. I have built a cal table from Ohms to Deg C, but i can only get the anolog inputs to see volts in not ohms? i have done this on the G4+ a few times with no problem, what am i doing wrong? Thanks in advance Dave

Hi everyone, I am just in the final stage of fitting and tuning an Xtreme to a LS3 powered Boss Hoss motor bike. the tunning is done and the last job is to set up a lumpy idle for the bloke. Does someone know the basic cyclic idle settings to get me started.. would be most appreciated Dave
