Is "fit a standalone" an acceptable idea ?

No!

[Exmantaa]

You wanna borrow my LSJ ecu?? Just joking, as I do not know yet if I will experience similar problems on the higher loads. Too bad the Z20LET ecu is still not running right. (Remember that some US tuner had a similar throttle-slammed-shut problem, but that was on a very high power (4-500+ WHP) LSJ or LNF engine...)

Is there a map swap at this point? I know there's a map swap at 2250rpm on the Z22 ecu which is giving me the odd problem. If there's a map swap and an obvious hole thats making it knock or run lean it could be shutting down as a safety feature. Do you have any knock retard measurements around this or a wideband lambda reading?

I don't want to go standalone yet I have put too much time and money into this conversion, I will do some research on the us sites about it shutting. Not certain if it swaps map over. It is not the TB, tried a z20let one same thing, S/c tried an m62

I just spoke to Jon and it sounds at the moment like it is specific to Nick's car, they should know more this afternoon.

I might be in need of a vxt loom anyone? it only uses one map so nothing there,

as it's set up for a different engine could it be reading engine vibrations as knock? or are these filtered out?

Shouldn't that just retard the ignition? Are there any fault codes?

[NickB787]

No fault codes at all

Since the beginning of this ECU swaps story I said I couldn't see how an iron block/cam belted engine knock filter setup could work without issue on an alloy engine with a chain which is waaaaaayyyyy more noisy.
Still I doubt it is the issue here, and if it is it should work by simply changing the torque of the sensor bolt or simply removing it ?

My guess is more around a MAF issue, do they use a MAF sensor as on the z20LET ?

Yes they do

[NickB787]

They might have it

[southpaw]

Fingers crossed Nick

[VXT Tim]

They might have it

Great news

[NickB787]

They have done it Thanks to Jon and the guys for all their hard work with this the real mapping has started

[techieboy]

Excellent. What was the cause of the throttle problem? Fingers crossed it's all plain sailing from here......

[siztenboots]

they moved the drivers seat further forward

[NickB787]

they moved the drivers seat further forward

was to do with software and the dump ( amal) valve on the turbo setup I am certain Jon will tell all when he gets time
