It was the 80's lets be thankful that its a digital system and not analogue! Fingers crossed I may have fixed the issue plaguing my car. I found a crack on the vacuum hose between the AFM and t-piece which spits to the entry of the compressor housing. The spit was at the t-piece end, I plugged...

Its been just over a year and I still haven't cracked this one, also struggling to find a second AFM in order to look at contrast. This night a friend and I back probed the car whilst driving, if anyone has some experience please give your opinions on the below results: Hot idle - 3.8v Cold...

Forgot to add, thanks that is great information! Also there are no codes to clear or reset but the "anti-lag" can be cured for an unspecified time with an ecu reset. BTW what can the ecu actually 'learn'? And the NE, G1 and G2 signals do they trigger the ecu on a falling or rising edge?

My AFM is behaving exactly as described by Asterix. The resistance measured across VC and VS is not monotonic and is much more like a wave but with an increasing trend. However, measuring the voltage output of VS is monotonic and decreasing with measuring plate opening. That is only half the...

The intermittent "anti-lag" appeared again today. What sub-system of the TCCS is able to retard timing so that it is able to perform like an anti-lag strategy? I'm sure this is a timing issue, as described above the AFR's during "ant- lag" are lean indicating an incomplete combustion as a...

I'll try this BUT I was a little surprised when I measured 20+ AFM's at the wreckers the other day and the resistance vs vane opening was as described in post one. I believe measuring the resistance is misleading but the voltage is accurate.

No body?

This is true. Problem: Intermittent poor acceleration, antilag like engine response during engine warm up and power surge above approximately 5200rpm. Detailed description: The engine will run fine after an ecu reset i.e disconnect battery for a period of time. After a number of random engine...

Ignition timing would be based on the AFM voltage would it not? If it was just based on engine speed how would the TCCS account for load and boost? So an update on the situation: I believe the AFM is fine. I measured the voltage at the VS terminal which proportionally decreases from ~ 4.9v ->...

Out of curiosity whats the timing referenced to? Just the CPS?

When measuring the resistance across terminals E2 and VS of a 7MGE AFM should the resistance only increase from fully closed to open? I am having engine trouble with my 1GGTE which shares essentially the same engine management system design as the 7MGE. Whilst trying to diagnose the system I...

The connector plug for the wiring harness? All I can do is check if IJ's harness will plug onto the LS1 coil I bought. Will that be sufficient? His plugs are from a GM Holden harness to suit a domestic over here.

On a 7M I would place the coils on the cam covers. IJ's setup makes sense due to the location of the spark plug on an LS2 and his exhaust manifold. Here are the dwell settings for the LS2 coils, again from Motec Aus via IJ: Batt V Dwell 8V 10.2ms 9v 9.2 10v 7.4...

Here are the dwell settings I received from IJ. via Motec Aus: Volts Bat Comp (msec) 8 12.6 9 11.9 10 10.9 11 8.3 12 6.0 13 4.9 14 4.2...

Hey Fred, Sorry for the late reply but i missed this message. I don't race triathlon, that picture is from a Japanese show. Google "hard gay" and you'll see the origins. Good to hear you enjoy the chit chat, I'll try crack the whip with Ian when nessecary. Rob

For anyone who has completed a G series diff rebuild could you give me an idea on what size pullers and bearing separators you used, in particular the following: 09308-10010 - Front oil seal and slinger (puller) 09556-22010 - Front pinion bearing (puller) 09950-00020 - Rear pinion...

A 2j would be as straight forward as a 1UZ, however the op is in search of significantly more displacement.

I think either way to reach your power goals you are in for alot of time and money. There are people with complete factory motors producing around 500hp on factory motors in Australia, with the correct component selection I would believe 650whp is possible. In NZ a F40 replica company was making...

It'll be a whole let more work for just a 4.5lt over the 4.0l. I dont know what prices for wrecked sc400's are in the states but I have a buddy here who just bought a whole car for $1700Aus. If you want more displacement cheap, this is the only way.

Dude you have soarer, make your life easy and stick with a 1UZFE. If the 500cc is a big deal go for the 2UZ, this way little fucking around.
