well hopefully there is no reason to need any logs from the module, but last time I raced it was fine till the end of second gear when I got a bit of a miss, then in most all of 3rd gear from about 3/4 track on it was missing......

was this the module having a spac, was it plug gap, was it the fact all my flywheel bolts came loose and it was causing a vibration in the motor that upset the crank trigger on the other end ?!?!?!

we cannot answer any of these questions, but with the module log if it happens again we'll have an idea if it was in fact a module issue or otherwise .....

I knew when I started using the module it was very much in development and there could be teething issues so if I can help by getting more data that might pin point an issue im happy to do that ....

having said that, I have not had an issue with top end missing before, and I have also not had the flywheel bolts ever come loose before, so theres too many variables :)

ok so where do i start .....

un-eventful trip to Sydney, absolutely freezing stepping out of the van, then 30 minutes later finished scrutineering and i reckon 10 degrees warmer!

first run out, it popped in the burnout and i was a bit sus about that, but it had been missing a bit on and off like a plug a bit fouled, i was hoping a nice flog down the strip would sort that out.

so sure enough the whole run was similar, launched hard then .. pop! next gear off we go again then pop!

so went back to the pits and by this time the thing was missing the whole way down the return road.... new set of plugs in and it was back to normal, so figured issue solved back to the staging lanes!!

2nd run same thing, i worked out by then it was getting to bang on 6000rpm and just shutting down, like all spark was lost then would pop and go again .... every gear 6000rpm pop!

so back to the pits and emailed VL400 ... screwing around, checking the rev limiter numbers in the ignition module tune and crank trigger and such ... nothing looked out of place, changed the rev limit to 9000rpm, revved in the pits, pop! 6000rpm :|

thankfully VL400 was on the computer and got a reply email in like 5 minutes, when logging the ignition module and revving it, at 6000rpm the error count would increase a heap every time.

so sent him that log and 10 minutes later the reply "you don't have a soldering iron at the track do you ?" FFAARRKK!! so got in the van and punched supercheap auto into the GPS! 30 minutes later and $50 we are back at the track with soldering iron, extension cord and a roll of solder!

the call was remove risistor 5 first, test then if it is still doing it remove capacitor 5 and re-test..... so removed R5 and plugged it in BROOMMM 7500rpm fuck yeah baby!!

so put it all back together and went out to the staging lanes for third run, which was a saga too .... had heaps of time to gather myself because i missed my lanes run by about 5 minutes, so in the car and strapped in with plenty of time and go pro on, data logger on, FARK sd card for it is in the laptop at the van ....

totally forgot to press record on the go pro, no data log, and hoping for the best, wastegate screwed in to the max and all or nothing was the plan at late enough in the day to possibly only get one more run if it doesn't work!

then doing the burnout, barely even into second gear and the car is heading for the wall! backed out, then stabbled it again, seemed to grip up ok so fingers crossed!

staged early cause old mate was slow getting out of the burnout and to the line etc, had it on the two step rev limiter for like 10 seconds, if thats not max boost off the line nothing is hehehe .... launched nicely, then on comes the boost and we are just g-forcing it up!! felt really good, started to catch back up to old mate, and then second gear just kept going strong, clicked third and ooohhh yeah no missing still pulling hard, and i knew it was going to be in the tens!

driving down the return road pretty happy everything just worked ... get to the tunnel and andra person pulls me up .... is the car teched - yes, do you have a suit - no, well your going to have to pack up mate you just ran a 10 .... hell yeah buddy happy to put it on the trailer :D

i knew it definately had a 10 in it but i was thinking 10.90 or something, when i saw the time slip i couldn't believe it!!

I will let VL400 elaborate on that, but I believe it is part of the primary pickup trigger circuit .... noise filtering or something...

yeah its got a 3.08 diff in it, I so wish I had the logger working so I could see exactly what rpm it crossed the line! probably could safely go to 3.45 but not sure if I could go much more than that without seeing numbers but was definitely still pulling hard across the line for once hehehe

the 60ft is heaps better than before, I think it was 1.74 or something so took a lot off it!

Great read there. I know the feeling trying to fix things, awkward soldering etc at the side of the track. Then awesome when it works!

delcowizzid - im not sure if its the same thing or not, VL400 might know, it was issues with it backfiring, but im not sure if it was the same cause or not ... it definately wasn't a full spark cut last time like it was this time, more of a misfire ... i now need full cage, flame suit and SFI helmet ... as for hunting 9's, i'll be happy to just get it back to the track in suitable trim to race before i worry about world records :)

Antus - yeah originally disgused with VL400 cutting the SMD resistor and CAP but didn't want to risk it not running at all so did the soldering iron run so it could be reversed if needed.... and like he said, i now have a soldering iron to keep in the race track kit :)

basically now its time for the gem to sit in the corner and rest for a while and i want to get the Bedford on the road, i also want to get a cooler for the gemini too and get that in before it races again.

i feel happy to park it at the moment, the 10 was niggling at me for so long i just needed to get it hehehe and the harness expires the end of this month so even more reason to get it happening before then!
