How the fuel gets into the cylinder, how the map sensor is seeing vacuum, how the engine managed to spin in the opposite direction to the starter motor,

From memory it cranked the right way then fired. God knows. Yavuz had no idea nor did Haltech. It did it more than once too. Thinking about it, I'd say it fired that early that the Piston wasn't far from BTDC, forcing the crank the other way. Trigger issue? Who knows. Pretty funny though!

[luke gtr]

Do you have a crank trigger Luke? curious

nope

I haven't had any issues with my PS2000, couldn't really recommend it more, though obviously there are others which have much the same features.

If you don't need it though, or aren't interested in it it isn't worth it. However I personally could never go back to an ECU without these features (power FC).

For example my car has been tuned many times. I recently dropped the boost to 18psi because reasons. Driving down a totally private road yesterday my car was at 18psi and as it turns out my AFR was 13.1:1.

If I had a power FC or even Nistune I would never have really known this.

My engine cut after 1s of this condition and because Haltech (and other better ECU's) automatically log this I was able to pull over and see why my engine just did that, and add fuel to the appropriate cells. Yes I have a wideband guage but I did not look at it. I also checked to see why the ECU was not automatically adding fuel to that area via the O2 controller. (can Nistune even do this?)

All of the above would just be ignored in a PowerFC world, and you'd be happily boosting away on 13-14AFR under 18psi and you would never, ever, ever notice until your engine decided to melt. Even after going to a tuner many times and being tuned many times on the dyno.

Am I paranoid a bit about this stuff? Yeah, maybe.

Maybe I've had more problems in the past than other people.

But getting a decent ECU, knowing how it (and your car) works to me is really a minimum requirement. I couldn't go back nor could I ever be happy not knowing, or recommending anything less. Anything less is "probably ok, maybe"

So what your saying is the Haltech leaned your engine out for no apparent reason then cut your engine, ok got it

[Kinkstaah]

Har har.

Cars are variable things and things change under the hood.

It's better to be able to see them before you feel the effects of something going wrong.

People only say "I don't need it, my Power FC is fine" until you do want a feature or your logs or safeguards catch something that is unmonitorable or unknowable with a more basic management system.

[Dose Pipe Sutututu]

PowerFC can't do wideband 02 feedback

/thread

even the likes of a No Frills Adaptronic can do it, cut power on lean out once it can't correct enough...

Leaning out probably wasn't the ECU's fault, probably lazy fuel pump, faulty FPR, fuel slosh, clogged filter, etc.

[Kinkstaah]

Nah it obviously wasn't the ECU's fault. The car was tuned on 24psi.

But it's saved me in multiple cases, like say 18psi when the cells weren't so well mapped. I've since fixed boost leaks etc. This changes tune. I've changed exhausts. This may change the tune.

I've also had a clogged fuel filter setting off engine protection due to lean.

Point being was, car felt fine in all of these cases but wasn't. Infact, it was dangerously lean.

I'd never choose an ECU without that function for saving a couple hundred bucks.

Auto logging when the car does something weird is a god send.

The features only seem un-necessary until you benefit from them once, and then they become must-haves.

Is the Power FC CAN Bus compatible?

I'm going to guess no. Not everyone has a need for CAN Bus compatibility but it's a deal breaker for me.

So does a Nistune with a small Windows tablet.

Did it consistently for me, it just advanced my timing when ever it wanted.

[Mick_o]

Consistency is the key!

DANGER TO MANIFOLD!

Yeah it's nice when you see your AFRs spiking to 15-16 when it decides to advance the timing 4 degrees more than it should. I suppose that's why its so important to have AFR feedback on a Haltec, to hide all its stuff ups.

[r32-25t]

My haltech does all sorts of terrible things, like start first time everytime, drives better then it ever has, gets great fuel economy even on e85, makes good power reliably and has rock solid ignition timing due to the ability to run a crank trigger

Yep what a shit ecu

My FC does all that except the trigger wheel, it doesn't have to use one, and 650km+ out of 60l and 11.1@123mph from stock turbos, what an absolute POS it is lol

Ignition timing should have no bearing on AFR from my (limited) understanding. Once the injector is closed AFR can't be altered yeah?

[GTSBoy]

Whilst ignition timing can't affect the actual total AFR, it can affect the amount of fuel that is actually burnt in the cylinder and how much might burn in the exhaust port, or down through the hole in the piston crown that just got burnt.
