  1. Where did you get the plenum made? Theres been an add on ebay lately for them.
  2. With my o2 sensor in closed loop my cruise driveabilty is poor. The ecu is constantly altering the a/f and varies quite abit depending on temps. I also have low comp and mildish na camshaft which doesnt help. Before my current setup i changed from a redline 4bbl manifold to aussiespeed and they are definitely a better manifold. I agree that its the way to go but it can be made to work for now.
  3. As for fuel system, something like a fitech fuel commander would be easy. Easy to rig something up with the same principles. Although a small surge tank is fairly simple to set up. Better to do it correct from the start
  4. Wouldnt the sniper kit allow the tuner to select a targeted a/f ratio. This will make the tune safe but not ideal for all out power. Set the a/f so the leanest cylinders are safe going off plug readings? Covers the uneven cylinder flow. Iv done something similar on my efi set up with xf banana manifold but mines turbo so rich is good for me.
  5. Afm has like a trap door inside that can jam shut. Have alook at that. Have u checked spark. Have they actually confirmed it getting to much fuel? (Wet plugs). People love to jump to conclusions and miss the basics.
  6. I have a te xflow turbo. Pretty basic efi set up and its more than capable on the street.
  7. Any idea on the camshaft in the stuffed motor. From my understanding for a turbo u want as little overlap at possible as while both valves are open backpressure in the exhaust before the turbo can be higher then the boost pressure and push the charge back into the intake. On a blower there is little to no restrictions in the exhaust so more exhaust duration and overlap helps the blower push everything out. In saying that my new slapper xflow turbo motor has a diffdrent cam with more exhaust duration and lift and it seems pretty happy. Im only running half the boost atm but feels good. This motor is pretty flogged too.
  8. Rnd 2 starting shorty. Just finished putting in a used 86da, .030 22cc ACL duralite pistons, backyard ported open Chamber xe efi head. Comp is around 9.1-9.2 with a different NA cam with more overlap. Hooked up the knock sensor into the front head bolt the same a late efi Xf. Il take it easy with this one till the tune is fat as I want it to last the summer.
  9. Up for sale?
  10. Spark plugs showed good colour, no audible pinging and a bump up in fuel pressure for good measure gave me confidence it was ok. I don't have a problem admitting fault. I had planned to use a well used 250 as a guinea pig but went with this one instead. I've done everything to this car from front to back and there have been lots of ups and downs. If it was easy we probably wouldnt bother or I'd put a Barra in. Aleast it was only a set of plugs and didn't go completely boom
  11. This log is from early on when i first got the data logger working. As i said i was in the process of fattening it up when coming on boost. Id say the damage was already done. The base tune was already in the chip and apart from maybe twice there was no audible pinging. I suppose me being impatient and not waiting till i could log a/f to give it a thrashing wouldnt have helped the process.
  12. U can see why i was trying to fatten it up when coming on boost. I had taken a heap of timing out of it aswell. This was done by road tuning not on a dyno.
  13. Data logger looked good although I was fattening it up when coming on boost. I'm using a xf efi inlet and have heard they have distribution issues so maybe that was the cause. Clean side of piston is the inlet sideim a little disappointed as all the other piston I have look like this and I'm not sure how they will go.
  14. Looks to have got hot on the exhaust side. Pinged a couple times when I first got it going. Ring gaps where enlarged.
