Nah, It was more of a rhetorical statement rather than a factual comment. Wasn't saying you said otherwise but just making an observation that if he had the second tune done at Dyson, it would more than likely rule out bad tuning.

Oh fair enough.

Completely agree :)

Maybe i missed it, did Dyson tune it the second time?

Dyson had done the tune befor i bought it and it was running great. But then i went and changed the top end then dyson retuned it for me and made 490 at 20psi. was running wicked under boost but too fuely at idel. Then i had a bit of a missfire. so i took it to the local guys. They said the tune was done the old school way and that they could get heaps more power. So they made me 430 at 24psi. YAY. And to fix the miss fire they sent the microtec of and said it was the problem. them said it was the harness so they replaced it. Then still missfired so they replaced my no1 coil for $40 that fixed the prob. Then they gave me a bill for near $2500 they wont give me a timming graph. Said they cant get that of a dyno tune. but ill scan the results from dyson and the results for the local boys T.A.S.

So you are saying you had 490rwhp then took it to another tuner and they could only get 430? nothing mechanical has changed ?

Link make the ECU which calls the shots on the fastest RB30 powered car in the world (may be the quickest RB in this part of the world not running meth too?).

So what? Cars that are even faster, much faster, don't have ECU's at all. So we should all change to that fuel injection system? Why not, based on your rating system, it's better than a Link?

Mechanical injection is superior to Electronic injection in nearly all applications...so yeah, we should all change to it.

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!

      You think its the AFM? I know its a common issues on R32s. I find it coincidental how this issue raised right after cleaning the fuel system. As everything except the fuel system was fine before. I tried running it with the IACV unplugged but did not notice a difference and still stalled. However, the RPM gauge is not in the cluster right now, so I will need to connect the laptop again and use Nistune to check the RPM. I will check this weekend.
