Alrighty. I just put my Power FC in, and unplugged the SAFC I had... now the engine will trun over, and start, then stall immediatly. If I leave the SAFC plugged in it start though.

Is this because the AFM goes through the SAFC before the computer? So I'll need to completely take the SAFC's loom out, and figure out how to wire the AFM back in?

or is it simpler?

Cheers/

pretty much...

you can leave it plugged in though.. and change all the tuning settings back to 0%...

Also if you reset it back to factory defaults (with the init function) you'll need to enter in the cylinder and afm setting i think..

remove the safc completey and restore back the afm wiring correctly.

then make sure you follow the self idle learn procedure correctly otherwise you may be stuck with a start-stall tune on the powerFC. the FAQ in my signature tells you how to perform the self idle correctly

read the FAQ

I have read the FAQ, the light went out after driving. The throttle sensor seemed to be the one playing up - I'll get it checked.

Just a couple of queries. When I advance that setting it says to +2 in the FAQ, my knock count goes way overboard, so I'm guessing I shouldn't do that. also, my air flow meter seemed to max out. I know I shouldn't be revving it to high. but I jsut wanted to check it out.. and it maxes out at about 5,500. Any ideas on that? Cheers.

      Unpeeling the Orange

      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.
