Turns out I was low on Glycol, and I overfilled my reservoir. So when the turbo gets warm it boils and over flows the tank(Worse when I was running BP98). Since I reduced the tank level back to where it's supposed to be, replaced the coolant and purged the system it has been stable(touch wood)

I understand how air pockets in the system would cause timing drift...would also cause incorrect mixtures in open loop. The thing is every ECU suffers from the same fate. "Incorrect data input causes incorrect data out"

Will it need head studs, pistons, trans replaced at some stage....yes I expect so. Am I trying to kill it, of course not, Am I trying to make as much power as I can-yes, Am I being reckless because I bought it with a blown turbo cheap-no

If you want to poo poo the EMU to support your link development, the biggest problem with EMU is injector timing. A stand alone will make more power, cleaner exhaust(less fuel smoke) and be better on fuel.

Shift timing is effected from the EMU boost cut clamp, the Shift kit doesn't really help the problem as the TCU try's to bring the shift points back in line with the Target MAP vs load input on the CAN line. If the Link will interface with the TCU CAN it will certainly help keep the trans alive. A TCU reprogram would also be a valuable investment

How's this..

I emailed Nistune Developments about the M35 and AFM failure frequencies here.

No one there ever heard of AFMs blowing up due to modifying and/or tuning, nor of M35 issues.

They thinks it's a design fault somewhere and sounds like it could be getting more voltage than it needs through it's power supply.

Suggested regulating the power source or try a GTR AFM..

Anyway worth a try.

If you want to poo poo the EMU to support your link development

A few EMU fitted cars have thrown rods recently... I knew about the timing issues when I installed mine and installed the Fcon as soon as I could. No need for me to 'poo poo' the EMU, every tuner I speak to does that without me saying a word, hence why no-one will tune it these days. Good on you for trying to develop it further, but the only reason I was installing them is, there was no other option.

A little support with our M35 Link development wouldn't go astray, it isn't about selling a heap of units, it's about getting a decent tuning option for those few of us pushing the limits. I know we will struggle to sell enough to recoup even a small part of the costs involved, and there are plenty of headaches with it still to address.

    • Didnt realise RB's had more then 1 head.
    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
