Mi Running On?

[daneldridge23 15]

Hi guys

 

I got my engine finaly started, starts fine and idles ok

 

the only thing is that when i rev it, it runs on for a couple of seconds?

 

i have checked the throttle cable etc, maybe its over fueling?

 

its on jenveys on an omex 600. its ecu came out of a running mi with the same bodies so the map shouldnt be a mile away i hope.

 

any ideas if i can adjust something in the ecu?

is it mapped to the engine?

 

is the engine rebuilt?

 

have you made sure 100% no airleaks

[daneldridge23 15]

hi

 

its not mapped on my particular engine no, but came of a running car so i cant imagine it would be like a base map from omex?

 

the engine is rebuilt completly and im not aware of any air leeks

what do you mean by "running on" ?

[camgti 56]

I think he means that when he dips the clutch to change gear ( For eg ) the engine continues to stay at a similar rev and not drop back like normal..?

I think he means that when he turns the ignition off, the engine stutters a few times before stopping instead of just stopping. A common feature of old carb engines before they started fitting 'anti-dieseling' valves to them. As you say sounds like its running rich. Does it do it warm and cold? I would check/swap the ecu temp sender. Are you running a wideband lambda by any chance? If so you should be able to check the mixture. Check that omex is set to cut the fuel off throttle too.

Cheers for the replys

 

Cams closest, basicaly when I rev the engine instead of it droping back at a steady pace to idle, it stays at a higher rev for a few moments then drops back to idle??

[welshpug 1,621]

ah, so the revs are hanging, rather than running on.

 

the term running on usually implies that the engine be it petrol or diesel fuel carries on running after the ignition is turned off.

 

your issue is likely to be throttle position sensor or air leak related, your best bet is to get it to a rr for mapping.

Can anyone recomend a good rr in the bedfordshire\hertfordshire area

no, but for the service down in truro, I will always take any of my mapping to sandy

Hi Dan,

 

Just to clarify, the ECU was running a base map provided by Spoox.

This was enough to get the car running, although it was overfuelling slightly, as I mention to you.

I never encountered any problems with the revs hanging. Have you re-calibrated the TPS because with the linkages coming off then back on, the TPS settings are likely to be slightly out.

And get a video up !!!!! We all want to see the project finished!

[daneldridge23 15]

lol im painting it hopefully next weekend got 4million jobs to d before i let you lot see any videos!

I would say that's the std map from Omex then, the TPS map does depend on where the original (Base map) was set so even if you set unless you match it to the map it will always be out.

I've got a map here which you can try if you PM me your email address, I'll see if I can send it over

 

As for mappers, give Omex a call and see who they suggest unless you fancy a trip down here

[daneldridge23 15]

would be trailering it either way so might take you up on that!

 

be easier than texting you at 10 every night trying to figure stuff out!

Mentioned it before, but yes.
