I'm STIIILLLLL trying to find the cause of this elusive slight miss at "just touching the throttle" sort of thing.

My ECU shows the brand new Bosch MAF is dead. But re-set it and it goes fine for a mile or even 100 miles before the slight miss returns at just on the throttle setting... Then it's as if there is no petrol splutter hesitate, foot down and whooosh, she's off like nothing happened.

Plug in, MAF dead, re-set and we're back to the start :rolleyes:

I've been told (as yo know from my witterings on here) it MUST be the LPG set up. Could be wiring, could be air leak, etc. But nothing concrete found!

What I need is a "live data" stream read at all throttle settings going through lights, slow runs fast runs hard up hill runs and so on as I am convinced something else it playing up and throwing a wobbly into the ECU.

I am broke as at the minute, so will need to wait a wee bit. But my question is can the Nano do a live data read over several miles?

Thanks all :)
 
Answer is yes, the Nanocom has a live data mode so you can drive with the unit on your dash board and data on display , at the same time you can save the data to a SD card and display it on a computer using a downloadable program, you can also put the data into an Excel sheet and graph it or whatever.

That's the ticket ;)

So, I will mostly be hinting to my wife, "See for christmas, I just want something small...nano small actually :eek: "

:D
 
HA..:p:p:p:p:p,Aye ....did you try carb cleaner on the throttle body And injectors to see if revs changed...

Not yet. Meant to get some, but not convinced as she idles beautifully somewhere about 700rpm. If she was sucking air surely the revs would rise up when warm...
 
On idle, it will compensate to give the correct idle speed even with a slight leak but it might be enough to underfuel it for a short while at slight throttle.
Also need to check your throttle potentiometer.
 
Detecting air leak is reasonably easy. You need a tin of brake cleaner and a sensitive ear. Spray product in areas that may have a leak (injectors lpg and petrol plenum beathers etc. Listen for a slight change in engine note. Simple. Air leaks are are a nuisance with efi systems downstream of the maf as they can alter the fueling significantly.
more oxygen entering the system after the maf leads to the lamda sensing excess oxygen. This is true for leaks from the maf to the the manifolds.
