Bloody limp mode again.

[Covo71]

Ok so went for a burl through the bush this morning and on the way back home about half an hour into an hour drive on the bitumen it starts going into limp mode.
Bugger was not the only thing I was saying.
FYI full nads done, HPD air box and MAF housing, exhaust, snorkel, K&N filter.
I think I have done just about everything I can to try and get around this limp mode.
Needing some on this big time.

Sorry mate no help here but these HPD maf housing things seem to cause more trouble then they're worth...

[Covo71]

It was going great guns, drives good heaps of go in it. Until today. It has been good for a couple of months. Might have to save up some coin and take it to a decent diesel mechanic that knows patrols (if I can find one) and leave it with them to fix.

There was a post here recently about these HPD housings dropping the MAF voltage by .25V therefore going to limp mode and the fix was to get a chip. I'll try and find it

I would check your MAF, its pretty hard to go into limp mode with the HPD MAF housing.

[Softy]

Dodgy MAF i think.. If you have had the HPD housing for a couple of months with no issues i doubt that cause it all of a sudden.

I have a couple of MAFs from Mudski (still waiting for address to send back mate) here. I wil, try again tomorrow. I don't think it is the housing at this point but I am obviously no expert. Lol. I haven't pulled out the MAF since I got back so I will check tomorrow and clean and see if anything comes off it.

I had a look at that article and indicates that if it lowers the voltage it should drop the power with less fuel but not limp

Yes I agree but I thought it might be worth mentioning to help

Try cleaning ur maf... I got the hpd maf housing and can see up to 27psi with no limp issues... Just recently It randomly started running crap.. Which I thought was a limp mode issue but ended up being leaking factory intercooler... He much boost are you seeing befor it goes into limp?

Yes you are correct mate. The hpd housing work, really well. Ive have great results from mine. But i had a DP chip too....

if your running a k&n filter you might be getting oil onto the maf sensor , jt just might need a clean , other than that perhaps it is spooling up a little too quick and might need the needle valve adjusting . hope this helps .

[threedogs]

Do you have a chip fitted ???
I think scott at DP tweaked the DP chip to suit the HPD maf housing.
But Im leaning towards a dirty sensor, only because it was fine before hand.
Check your oil levels too the mighty ZD30 doesnt like being overfilled

[Covo71]

I am not sure if this is causing a problem but when looking for issues I found the pipe from the MAF housing to the turbo is perished and cracking. Can't tell but it may be sucking in air. Found these on fleabag but it says eliminates the air intake resonator. What does it do anyway? Anyone seen these or used? Looks like it should make airflow better with a smooth pipe. http://www.ebay.com.au/itm/Patrol-GU-ZD30-turbo-Intake-Induction-pipe-UPGRADE-Performance-BLACK-/291492511831?pt=LH_DefaultDomain_15&hash=item43de4ec057

[threedogs]

you will be sucking extra air, I've made a larger intake but yet to fit it.
Replace the hose and any others you find , if ones gone others maybe as well

Read post #10 in this link. A chip might help. I ran a DP chip with the same setup as you with no issues. The intake pipe on my Di was cracked too, I was making a new intake pipe for it, but now the motor is coming out, for good....
