performance chip for VX?

[Doctor Bob]

actually it can do a bit more than alter the timing and dump fuel in, even the VN system, a pretty basic system has hundreds of parameters that control the car, then you get into transmission control as well, then a really complex system like the PCM32 that runs the LS1, there are thousands of adjustments in these.
A car blowing black smoke does not mean its making good power, it means its not burning all the fuel so its not efficient, race cars require a different tuning strategy to road driven cars..

Rob

 

[jules]

what other functions can it control?

yeah i know it can control the shift strategy (not on a VN tho) but that's not making Hp.

 

[krawczuk]

the chip can't really do anything else other than alter the ignition timing. dumping fuel in is exactly what it does from what i understand, that's why you see V8 supercars with black smoke coming out the exhaust a lot - this makes power. running stoichiometric is great for the environment but that's about it.

hi, yes thats correct vy,vx etc use a flshprom.
in the U.S you can get programmers that plug into the obd port and are tuned via a hand controller.
first u download the flash contents into the programmer, then via a set of yes / no buttons you can change the contents , then download the perf changes into the flashprom.
but as far as i know, these programmers require you to enter the vin number m so that the programmer will be able to make the correct changes...
vin number tells you diff ratio,trans type, engine etc.......
and there for e i dont thinl they will work on the vx etc.. commodores.

yeah i know it can control the shift strategy (not on a VN tho) but that's not making Hp.

Just to give you an idea...
this is whats controlled by a VN Memcal,
this is the simplest of the Holden Calibrations.lol

"yeah it just controls spark and fuel....."

[jules]

apart from the air-con, those are all spark/fuel controls aren't they?

 

[Doctor Bob]

IAC, Fans, Malf codes, TCC, Speedo constants, among others

The point i was making is its not "just"
more fuel..less fuel, more spark..less spark
its far more complex than that

Rob

 

[jules]

but those controls - IAC etc are in the used to simply regulate how much fuel is pumped in to the engine.

i know it's reading a whole load of sensors - but you aren't paying $1000-or whatever for a chip to read stuff, you're paying for what it actually *does*. and in the end, it really just decides how much fuel to pump in, and spark timing.

question for dr bob
