That's a decent enough cam, would need some 35-40 lb injectors, L67 ones should be enough but no harm going bigger. With the idle screw, it needs to be set so the IAC steps in TP once fully warmed up and settled to be about 20 steps. Using the screw to adjust the idle is a no no as the ECU will try ...

Yeah, that's the stock late VP and VR injectors, 11p/12p stock data is for those as well as the 917s from earlier cars. So that should be all good then. What are the cam specs? The stock injectors would be borderline big enough for anything more than the basic baby/"stage 1" upgrades, espe...

Whats the PN on them and colour of the tops?

I have not much problems leaving the setting stock, but a bigger cam with lots of overlap likes lean and will abruptly stall if too rich at cold and during warm up. Bigger cams also like heaps more timing at idle and light loads. You can just adjust the idle table and overlapping main table spark ce...

Yes, that def would be the reason. If it's not lock up, the ECU will be cracking the shits for sure.

My understanding is rpm range is primarily dictated by CPU resources and clock speed fighting the ever decreasing window of time available to execute instructions as the rpm increases. Table size of a few rows would only be a few bytes I'd imagine?

Is this a processing limitation because the code has a lot more stuff to executed in 11P compared to 12P? I assumed 424 and 808 have essentially the same CPU?

I suppose you could but I'd expect that it will continue to get worse with time and need readjusting to compensate. As for my bothers ute, I am sure it went into trans limp mode when that happened and was forced into 3rd. So I just turned off the DTC processing code flag and it drives fine as far as...

Can't use 12p instead and run 808? They go to 9.6k standard.

This is the torque converter clutch slipping, basically the converter/auto is on it's way out.

My brother's ute was doing this on his 2nd auto, so we just added slip additive and then turned off the code in the tune and hoped for the best.

Still going today but the ute has def seen better days.
