Phat VR6 3 Posted October 15, 2009 Report Share Posted October 15, 2009 fair play. always fix what you knows broken first.so whats left? Link to post Share on other sites
legvw 0 Posted October 16, 2009 Author Report Share Posted October 16, 2009 Well swapped leads over and its still miss firing, took plugs out and they are black, sooty and soaked in fuel! Took out dip-stick and oil smells of fuel, so gotta do an oil change, and reduce the fuel.When the ignition is switched on, the fuel pressure rises, then drops to 0 when the pump has stopped priming, is this right?Also, do you have to set the fuel pressure to 3 bar at idle, or should it be lower?Just trying to work out whats causing the over-fuelling, as the base map is set-up for 360cc injectors, and i've got 440cc injectors. Would this cause it? Or should i drop the injector openning time across the map to compensate for the larger injectors? Link to post Share on other sites
Phat VR6 3 Posted October 16, 2009 Report Share Posted October 16, 2009 I really don't know for sure dude. but this i my opinion The map will open the injector for a curtain amount of time, It wont compensate for injector size as it has no way of knowing there's different injectors fitted.So as you said, the 440s are letting more fuel though than the 360s would. so you need to cut down the amount of fuel its letting though.Surly they should have sent you a base map related to your injector size?

AJmk2 2 Posted October 16, 2009 Report Share Posted October 16, 2009 Im not a 100% but , fuel rail pressure should remain constant all of the time. The fuel should be adjusted through your injector opening times.If you flood brand new plugs it can kill them straight away. If you changed your injector size definatly recalculate the opening times. I dont know if its like on megasquirt but on there you can find in your base set up parameters injector size and you can just change it there which automatically changes the rest of your maps but still will need minor adjustment.

jims13 6 Posted October 16, 2009 Report Share Posted October 16, 2009 fuel is your problem.. if its setup for 360's and youve got 440's you got way to much fuel.. you need to drop it loads, if your on standalone, or chuck some different injectors in , if your on a chipped ecu like mine Link to post Share on other sites
legvw 0 Posted October 16, 2009 Author Report Share Posted October 16, 2009 Thanks for the replies.Been studying the emerald settings, and found the injector re-scaling. This should sort out the over fueling by adjusting the whole injector map according to the type of injector i'm using.You're right jim, there is a big difference! Just had a play and it adjusted the whole map down by a third after the re-scaling!! Mental!I think it did muller my plugs, so i've got some NGK BRK7E to go in sunday.

jims13 6 Posted October 17, 2009 Report Share Posted October 17, 2009 yep a massive difference.. around 60 % ish.. you could try burning the fuel off on the plugs. its abit pikey , but does sometimes work .. although it will result in small fire Link to post Share on other sites

Different size injectors behave differently at different throttle openings so ideally you need to get it setup properly on a dyno if you get the time and can afford it. It should get you close though and if you're using closed loop, that should tweak it further.Well done on getting it all in and fired up so quickly :-) Link to post Share on other sites
legvw 0 Posted November 1, 2009 Author Report Share Posted November 1, 2009 Been having a few issues, apart from having a serious dose of the flu, my laptop and my ecu just won't connect.I've bought 2 different types of rs-232 to usb converters, used 3 different drivers on each and still nothing!Really getting on my tits now :-( Anyone got any advise, please???

kcw 1 Posted November 4, 2009 Report Share Posted November 4, 2009 Awrite I know this off topic now but how come you only removed the spare tyre section instead on the whole boot floor and exhaust tunnel? Can you still run the standard syncro fuel tank the way you've done it or do you need to swap the whole floor like John is doing?Ken Link to post Share on other sites

Can you still run the standard syncro fuel tank the way you've done it or do you need to swap the whole floor like John is doing?Ken No you can't run the syncro tank because the boot floor won't be high enough, but the tunnel is fine to run a prop and exhaust. I only cut the spare wheel well out because i wanted it all custom and didn't want to try and source a syncro boot floor and cross brace. I found it easier and cheaper to do it my way, as i'd done the syncro conversion on a mates mk2 a while back.Hope that helps! Link to post Share on other sites
