lol never even thought of ebay! that links to an invalid item number now joebaby83 looks like its been removed lol. tbh im in no great rush with it other than just wanting to drive it again, ive still got to do some paintwork, change the rear cones and hi-lo's, fit the intercooler, and numerous other jobs, plus i cant realy afford to insure it for a couple of weeks so ive got time to sort it i suppose! cheers for the help!

lol its likely to be a bit of both alex, the fueling is all to buggery untill i can get the bloody carb to clear itself out. erm once i can work out how the hell to take a pic of the program like boosty has done i'll post up the current map, i think it certainly wants some more advance on the lower kpa values because the highest advance fiigure on it is... 36 and everyone else seems to be up near 45 - 50 i just didnt want to up the figure to that amount and watch my engine go boom lol. i'll sort it this weekend, i'll just keep messing till it goes well enough to get me to a RR, it needs setting up now the intercooler and engine work is done anyway.

screen dump using the "print screen" key then paste it into paint, save as a jpg or whatever, crop to suit and jobs a good un

ah! cheers iain, will do it now

edit

just click on it to enlarge,

thats the map that was in it, the only changes ive made are on the 70kpa line, where there was a figure of 1 at 1k revs and 50 at 7000 with a gradual build up inbetween, which just didnt seem to corispond with anything else anywhere? any pointers or general help would be much apreciated! ive got the jolt hooked up to the pc now so i can make some changes,
cheers

hmmm thats not the map I thought you had LOL

thats the test map I use to check out the MJ unit.

either way.... it will work.

But you MUST sort the fueling out 1st before you map the ign.

what does the runtime display thing do has any one used it?

no longer a series, but still 1.3 turbo.

just apears to be what it says, takes the readings as and when they happen? if you click on it its the same map as your running, but it highlights the box its curently taking values from i think, if you try it with the megajolt hooked up but not running, the highlighted box is the 100kpa on the first rpm setting. states actual kpa too which is 102/3, also gives the amount of advance, rpm reading and some other info, although i dunno what actualy works because i cant see it while the enignes runing at the moment :S
aye thats first priority this weekend alex, its just bloody annoying because i cant for the life of me see what the hells up with the carb, ive had the float bowl off god knows how many times now and i still cant find anything wrong, last time it ran shite for ages and sudenly went right one day, daft as anything.

t piece trick?

anythings worth a try! i'll give it a good clean out today while im messing and i'll give that T piece trick a go too, im just getting fustrated with it now!
steve

doh! why did i start messing with it!

wohoo we have success! bloody minis, went up and started it today, and bang! ran perfect, no misfire, no chugging, and its idling nice and steady. anyway had another couple of go's up the road with it and after a little fiddling its running pretty much spot on!, ive only managed to get it up to 3rd at the moment because the test road is only about 200m long but so far so good! gonna go back down tonight refit the front end, and take it round the block. but it pulls like a train all the way through so im well happy with it!
look forward to getting it to a RR and finaly getting the boost up to a healthier level

doh! why did i start messing with it!

told ya!!! did you nitice it will rev up and down a lot quicker to?? mine sounds like a bloody bike when you give it some!!!

lol yeah lovely responce, well had a few more runs with it and all seems ok in the ignition front, i seem to have a problem with the fuel tho, its fine for a few minutes driving, then it starts to hesitate on boost, and finaly it just gave up altogeather, theres plenty of fuel getting through the filter, to the carb, and theres plenty of fuel in the tank, so im a bit stumped. its got me thinking either regulator problem or float bowl problem :S ? it just seems to run out of fuel totaly and the enigne cuts out, its possible to restart it and crawl along in 1st or 2nd but any heavy throttle or boost pressure just kills it again,
steve

doh! why did i start messing with it!

hmmm. does it do it at different points or same time every time???
i have had the problem of the float bown emptying quicker than the pump can fill it.

balls to the blower!!!



1330,stage3 head, gt1549, canems ecu, S/C box and drops

it lasted about Ooo 4 miles this time, then started to loose power on boost, then wouldn't pass on to boost, and finaly just splutered out, it certainly feels like the float chamber isn't filling up enough, it'll sit there happy as larry idling away and the longer i leave it the further it will drive again but it only manages about 1/2 a mile before it needs to stop and refill :S
i'll investigate it a bit more this week, im just glad it ran as well as it did while it was going!
ive still got to refit and repaint a few parts so im in no rush realy, i just wanted to get it mapped up a little this weekend and ive managed that so im happy enough!

Get a fuel pressure gauge tee'd in to the line from the reg to the carb and see what the fuel pressure does as it dies out....

also as soon as it dies, if possible check the return to the tank. if its pretty feeble then i would go with the pump, poor supply, or goosed pump etc.

i fitted a brand new one and my problems went which were similar to yours. i couldnt go as far as 4th gear, only upto 3rd.

hope this all helps steve. you can get a float bowl extention from avonbar if it turns out to be that. the pump sounds the prob now though in my eyes.

hmm yeah will definately get a fuel pressure guage, it wants one anyway realy. i'll give it all a good look over, the pump is only about 6 months old but i dont suppose that guarente's anything!
im sort of wondering if theres even enough fuel in it to run properly, i put a fiver in it on saturday, and it drank it all just pottering about testing it, so i put another fiver in yesterday, and thinking about it i dont rememebr the guage going down any all day :S. wonder if its stuck on 1/4 and im acutlay almost empty. i'll bung some more in it just to be sure!

doh! why did i start messing with it!

£5 wont last long! always better to over fill it for now.

lol! yeah seems to run a bit better with some petrol in it! bloody fuel senders gone caput. comes down to 1/4 and stops, bloody thing. well fingers crossed it seems to have sorted that problem, i want round the block (about 2 miles i think) and it didnt do it again. only problem ive noticed now is a bit of hessatation as it comes on boost, which i think is down to the timing, if i give it full power, it will run perfect right through from 2000 - 6000rpm, but if i use light to middle throttle it wont pass onto boost, it just boggs down and wont generaly do anything untill its wound back up again with more throttle, and it wont realy cruse very well, off boost its not too bad, but again if its just off or just on boost it dosn't like it.
i'd be greatfull if someone can try and explain to me what areas of the map i need to be looking at changing.


thats basicaly what it looks like now, there might be one or two figures different but i never saved the last update to my folder i think theres maybe a tad more advance on the 230kpa row. any help on what best to change would be most apreciated.
