Hi all, got the 1.4 all TB'd up, and had it running breifly a few times, but running like a bag of sh**e really having issues, think the map is about as accurate as the Sun reports on sky news. Does anyone in the area have a clue about mapping for a base map they could send
All the sensors are fine
P.S Have had flameage out the inlet side twice now due to slight over fuelling. I really want to keep my eye brows so please help me
If you are running emerald why not spk to Dave Walker? At least that way you can be sure that the ECU is set right which should help make it clearer to find out what the problem is. In any event arent you gonna need to get on a dyno to get the basic mapping for full power before you start to refine it?
You're probably right but have spent all weekend plus one "cough" sick day and have so far had poor results, it's not my wiring but the ecu keeps like cuttingout for a split second then coming back to life again, but I'm not sure cause I checked the wiring a few times, Have had a few lengthy phone conversations with Karl at emerald about it today and has suggested a few things, but we can't get the car running stablely, we can't get it running enough to get it up to emerald for a tickling there. What management are you running on??
The only way to set it up properly is pay somebody who is experienced in mapping emerald ecu's to map it on a rolling road.
It can be quite costly as it can take a good few hours to get perfect.
A map from the exact same setup in a different car will work on yours,but still wont be perfect as EVERY engine is slightly different!
When going for TB's and programable ecu you should allways allow £200 or so for a good rolling road mapping sesion,once done it will only need doing again if the stup changes,like changing the cams or exhaust,any kind of tuning or change.
Further to my PM
If I get a brief cutout it has always been dodgy crank sensor readings so far. I dont know what you are using but check that have got the clearances between the sensing wheel and the sensor close enough cos if isnt you will be getting alsorts of rough running problems. They generally need to be nearly touching i've found to get reliable readings. Does emerald have a log to check for historic errors? You may find that the crank sensor itself is unreliable - I 've had 1 go.
What Lambda sensor you using? If its a Lucas one throw it away and get a good one.
re wiring - I had a problem in the actual ECU connector. I only found it doing continuity checks on every sensor and its wire to the ECU side of the main connector. It looked to be soldered in fine but wasnt. Was getting intermittent water temp failed readings
i had flames out the tbs too on 1st start up, turned out to be the rotor arm had got jammed and was stuck about 30 degrees off its normal position. so sounds like you have the advance map way out somewhere. squeeks from the inlet would be underfuelling by the way, i used to get them on part throttle with the supplied base map.
i would have a crack at uploading an ignition map for the 1.6 16v and then knocking 10% of that fuel map too if anyone has one to give you.
agreed about the crank sensor, make sure its a good one.
We sat down last night to reveiw the maps we were using to get the thing running, and one had a crazy ignition map on it so we are not using that again, and are going to use the std 2L XE map as a safe base to start form as the ignition advance is fairly low. It also apears that DanJ managed to not hook up the grouns for the crank shield so that's why it kept loosing the signal to noise. we are gonna try it again after work an hope to get a stable idle.
the lambda we have is a 4 wire NGK jobby from Dicko. Still the singe marks in the sound proofing give the engine bay characterlmao
I'll keep you guys posted.
thanks for the input
We have the telltale to 5500rpm, it just seems to cut out every half second, ECU clicking like a good'un. The sound is wicked, but Danny forgot the camera so now footage of the flames. He'll have it when the other engine fires up for the first time
Look out for it next week
P.S If you map a point say throttle 2 speeds 6k, load 2 with a spike in fueling can you get a flame out the exhaust when you change gear??? Not asking for me but Danny wants tpo be able to have a map for impressing the ladies (poncy bugger) I think the sound is enough myself
Just to give an update, the DIS pack wasn't wired quite right *cough*DanJ*cough* but now it runs fine, got a stable idle at 800ish, and then went out to see what we could do about the map we were trying to use. After some minor adjustments (reads co-pilot getting push button finger from triming it so much) the car was fine, got to a straight bit ans hammer down, not leaning at all all the way to 6200 cause the ARP aren't in yet, but compared to the way it was before Much better.
then off to Girlfriends as she hasn't seen me in days (Got some kissing up to do there) to show her, she came back to mine in her nova with 1.4 8v MPi in a std shell, not very heavy and we could get away and with her in front we could just about keep up with her but not catch. But it's running pretty rich at the mo so lots of work to do. Thanks for all the input and help. CP is that offer still open???? Would be great for some experinced eyes to have a look.
CP filled me in that you were having some trouble, I've got to grips with his map now, and I'd say that its pretty much spot on. If you want I could have a look and compare our 1400 map to yours and come up with a decent one for you. Might take a few hours to get it right, but its good fun and rewarding. Let me know.
Where about's is CP's? My car isn't road legal at the mo (no MOT) Danny's is the running one, and he's being a mincer about turning up. If you can do anything on a car that is static which I guess is a not then it's probably gonna have to be weekend after when fingers crossed the nova is back.
