Marty Posted December 14, 2006 Share Posted December 14, 2006 Ive started my supe up, after putting a basic map in to map the ecu etc. its a bit smokey, to say the least, the smoke is a blackish blue colour, ive taken a vid, on my mobile to try and show everyone, so i can get some feedback. Am i right saying this is a fueling issue? overfueling to be exact? Or could it be something else? Bear in mind the engine hasnt run for 10months im suprised it started, i cranked it for 30secs without the fuel pump fuses in, to circulate the oil, then put the fuses in, and it started 1st time its idling very low, 400-500ish, but this is because the ecu is still trying to sort out whats going on i assume (its been asleep 10months too:)) its a poor vid im afraid, camera phones dont seem to be the best of quality CLICK ME Quote Link to comment Share on other sites More sharing options...

uk-rich Posted December 14, 2006 Share Posted December 14, 2006 working now, i'd say defo over fueling there, was it cold (just started) when you took the vid Quote Link to comment Share on other sites More sharing options...
Wez Posted December 14, 2006 Share Posted December 14, 2006 What ECU is it? Have you got an AFR gauge? Quote Link to comment Share on other sites More sharing options...
Marty Posted December 14, 2006 Author Share Posted December 14, 2006 its a MAP ecu, ive not wired in the afr gauge yet .. But i can see what it is if i plug my pc software in to the ecu, heres a screenshot... afr is 17.9-18.1 on idling. rich... it was cold yup, doesnt seem to change when it warms up though? think i have an airlock in the coolant too, its staying nice and cold when the engines getting warm Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted December 14, 2006 Share Posted December 14, 2006 17.9-18.1 is not rich!! something not right there. Quote Link to comment Share on other sites More sharing options...

uk-rich Posted December 14, 2006 Share Posted December 14, 2006 have you looked at the condition of your plugs Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted December 14, 2006 Share Posted December 14, 2006 I'm still trying to watch your video, but on cold start the ECU should be running at anything from 11.1 to 14.7 depending on ambient temp. OK watched video now, that defiantly looks rich! i can only assume that you lambda is not reading right, is it calibrated? what make is it?

Marty Posted December 14, 2006 Author Share Posted December 14, 2006 have you looked at the condition of your plugs They looked pretty good when i took them out their boxes,before installing them, the other day My supe was a lil bit smokey before i did the single conversion, i put it down to the turbo seals, as it had all the turbo seal characteristics, worse on decatted etc, but another member, ellis, had similar issues to me and his turned out to b the piston rings. Wonder if thats what mine is? It was never this bad when running the twins though, only a puff of smoke now and again, when idling etc. Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted December 14, 2006 Share Posted December 14, 2006 Sounds nice, even if its very smokey Sorry, im going! Quote Link to comment Share on other sites More sharing options...
Alex Posted December 14, 2006 Share Posted December 14, 2006 Yep cold start should be in the 11's and warm up to 14.7:1 Quote Link to comment Share on other sites More sharing options...
Homer Posted December 14, 2006 Share Posted December 14, 2006 could it be a major boost leak causing the overfueling? The boost pressure on that screen shot shows zero and that may explain the incorrect afr reading too. Edited to say I mean a leak in the fmic pipes, not boost leak Quote Link to comment Share on other sites More sharing options...
Marty Posted December 14, 2006 Author Share Posted December 14, 2006 OK watched video now, that defiantly looks rich! i can only assume that you lambda is not reading right, is it calibrated? what make is it? Ive got the standard sensor on the downpipe, the o2 one? is that what you mean? The only other sensor on there is the aem wideband sensor. pic attached of the two sensors.

The boost pressure on that screen shot shows zero and that may explain the incorrect afr reading too. i thought maybe a boost leak? everything seems ok though, i'll have to recheck my pipe work i guess i did do some of it in a rush edited to say... i knew what you meant Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted December 14, 2006 Share Posted December 14, 2006 OK it looks like the AEM wide band sensor is the one nearest the turbo? i would be inclined to swap it over with the std one, they don't like getting to hot, whats puzzling me is the fact that its putting what looks to be rich mix smoke but the lambda is saying its weak! now it could be that the sensor is getting to hot but i doubt it on idle, or it could be rich enough to be unburnt fuel causing the wide band to see it as weak! i guess it could be a leak which would upset the AFM and subsequently the mixture, but the ECU would try and pull it back to stoic.

Marty Posted December 14, 2006 Author Share Posted December 14, 2006 Sounds nice, even if its very smokey Sorry, im going! It sounds lovely, although i dont think the neighbours will agree, espec when im setting off for work at 6ish in the morning :D Had a very helpful PM off foodfreak, saying it may well be because the o2 sensor is not man enough, and the map ecu needs a feed from my wideband to get better readings. So i'll wire that up asap and see if that helps any OK it looks like the AEM wide band sensor is the one nearest the turbo? i would be inclined to swap it over with the std one, they don't like getting to hot, whats puzzling me is the fact that its putting what looks to be rich mix smoke but the lambda is saying its weak! now it could be that the sensor is getting to hot but i doubt it on idle, or it could be rich enough to be unburnt fuel causing the wide band to see it as weak! i guess it could be a leak which would upset the AFM and subsequently the mixture, but the ECU would try and pull it back to stoic. The AEM wideband is not wired up or plugged in yet, as i thought it was just a standalone monitoring unit and didnt think it needed to be wired into the map ecu to provide more accurate readings . I cant swap the sensors around mate, they are different fittings. defo something strange going on Maybe my standard o2 sensor is more fooked than a big bag of fooked things, on a fooked day? That would cause problems wouldnt it? Quote Link to comment Share on other sites More sharing options...
Alex Posted December 14, 2006 Share Posted December 14, 2006 I assume the MAP ECU needs a Wideband feed! The stock O2 sensor should be up near the turbo...the WB02 should be about 2ft away, min. Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted December 14, 2006 Share Posted December 14, 2006 Ahh its all coming to light;) first off don't believe the read out for the std lambda as its no very accurate, second it is only meant to tell the ECU if the AFR is varying from stoic 14.7 AFR also its signal should not really have any adverse affect on the ECU as its in effect just a switch, is the ECU stand alone of piggyback? you need to get your AEM wired up and running, also you may risk killing the wide band sensor if you have not got it powered up with its heater on:blink: Quote Link to comment Share on other sites More sharing options...

The stock O2 sensor should be up near the turbo...the WB02 should be about 2ft away, min. I can only assume these are the correct positions for these sensors?? its a PHR downpipe, the sensor holes are designed for a wideband and a standard o2 it says, i cant swap them? QUOTE OFF PHR WEBSITE.... Includes Toyota oxygen sensor flange and 18mm oxygen sensor bung for wideband. Quote Link to comment Share on other sites More sharing options...
Alex Posted December 14, 2006 Share Posted December 14, 2006 Ok but like Ricky says, you'll kill a wideband sensor if it's left in the exhaust whilst not connected to power. Quote Link to comment Share on other sites More sharing options...
