Yes indeed cu @ the lakes 10.30:)
Thought I would post here as I think mine is not 100%. I thought I would disconnect it to see what happens. As I have been having some very poor auto gear changes since having the auto rebuilt. Also driving up Mt Hotham the other night I had to use low range.
Power feels better and there is slightly less lag. But the best bit is the auto seems to sft better. It's still crap but better.
The down side of this power is the EGT go thru the roof. I am assuming my ems2 with egt is setup correctly. And just resuming cruise from 60km/h to get back to 100. With get in excess of 750c.
So unless you can monitor temps. I would be cautious on using all the extra power.
I am going to attempt to clean my MAF tomorrow. But also search for a replacement.
Hi turps,
CRC do an maf cleaner now, but contact cleaner also works well. Make sure the MAF is cold before cleaning otherwise you could fracture the wire. Also ensure it is throughly dry before reassembling.
If you can get access to a nanocom or similar it will really help with the diagnosis, alternatively using a multimeter to check resistances across the pins will also give you an indicator as to whether it is stuffed or not. Otherwise you will be shooting in the dark and a MAF is not cheap!
That said from what you are describing there may well be other issues besides the MAF causing your problems.
Good luck
Steve
If you haven't done so already, get someone to reset the adaptations in the Auto ECU. The primary purpose of the adaptations is compensate for wear in the transmission clutch packs so need to be reset when you replace or rebuild the auto. While it won't fix lack of power it should help with the auto shifts.Quote:

Also brought an aftermarket maf from the uk. Think I went a little to cheap. It has fixed the lag on take off. So back to normal there. But as soon as I use more than 50% throttle. I get a massive miss.
As soon as I disconnect. I no longer get the miss. So I don't believe it is an oil in the loom issue.
Anyone got any tips on where to buy a new one?
As I kinda need it fixed. So I can sort out my auto issues. So will most likely buy from someone in aust. As I would like delivery by Friday.
The miss is most likely an overboost situation, you really need to get a nanocom or similar, this could all be solved very quickly and at little cost to you with a diagnostic tool. (and with all our help of course:))

Pretty sure not over boost (boost gauge not hooked up yet). As I have had the over boost thing before.Quote:

X2 Justin's comments regarding plugging in a nanocom or similar. It could save you a lot of time, frustration and $. I can't help feeling that you have another issue besides the MAF sensor, which an electronic diagnosis could well reveal.
Have a look at the first thread in the electronic diagnostics forum (members with diagnostic equipment). There may be a forum member near you with one who will be able to assist. Offtrack (Paul) updated the map of members recently and the link to the google map is on the second last page of the thread.
Good luck

New maf. Drives nice. Romsey LR even checked the ecu for faults. And there was only one. And it was due to the auto.
Reading this has convinced me to check my MAF as my fuel consumption is very average (17-20L/100Km!!) and my EGT's are high (if i don't watch the gauge they can hit 1000degrees!!!!!) and i have to religiously watch the EGT gauge. Also of note is the standard ECU will push it up to 750, so not sure if that is normal for a standard ECU??
Is a 2000 disco td5 auto with bar work, susp lift, 31 inch tyres etc, D2a intercooler, mandrel bent exhaust and remapped NNN ECU.
Hawkeye connected and showed about 59 at idle.
Checked the resistance values and i got:
pins 1 and 2 = 16.85 k ohms
pins 1 and 3 / 2 and 3 = between 2.9 m ohms and 5.9 m ohms.
I know there is a general consenus that I shouldn't ditch it just by the resistance values, BUT, from what I have read through searches of posts, the second values are WAY out of whack..
Would I be correct in thinking those values are too far out and I should buy a new MAF???
