Dyno Results from teh 25th November Dyno Extravaganza

Those are some huge torque figures . Mines only 188lb/ft

And it runs on stock ECU

.. And there you are with your fancy standalone

How's that even possible.

And I think there's some Engine management envy here .

I keep saying this... The Toyota ecu really is something else. It's got cleverness hidden in it well beyond our understanding. It is immensely flexible and intelligent.
Much to our detriment,or if you can harness it, much to our benefit

@shnazzle Do you think the standard ECU works against NA tuning but actually helps (up to a point obviously) forced induction?

I think it's fantastic at both. If you let the sensors do their thing, it's as flexible as an ecu could be. Start feeding it crap (maf/intake changes, o2 sensor changes, etc) and it loses it's ability to adjust correctly.

Doesn't the PE kit just use the stock ECU?

What about with a piggyback though? Would you still run one now?

No
Correct me if I am wrong but Helens injector duty is way less with standalone than it was with unichip. That's the stock ECU getting involved right there.
And i am having a mare with the 1mz ECU and the det3.

Yes. I still run one. But it adds a layer of complexity.
Worth discussing in another thread instead of messing up this one

It's the torque that makes the TTE setup tick most of the boxes for me, just shame power runs out top end

The hass setup is very raw and powerful

It's good keeping the thread alive for reference

[spit]

Good to see this thread again. Nostalgic!

Apologies for backtracking a little. Haven't been on for a few days.

I've nothing to add about the dyno day really, except that it was really good fun 

What on earth was the c2 setup made out of??

Bigger turbo.
Have seen spits at ding day.

Nothing special about the turbo unit. Same as the Hass. GT28R.

Gaspar's approach to piggyback mapping was always a little maverick though. He cut his C2 kit teeth on Celicas and then discovered the '2. Here he is having a quiet day out:

Unlike the Hass and others, he didn't bother with ignition adjustment - the EMBlue just juggles the air and fuel maps. Seems to work.

The logic he relayed to me is that the stock ECU is still in play and has plenty of versatility. My map has never been quite right from the off since I started drifting from the original wastegate settings (6psi) with a turbosmart MBC - it runs way too rich after an ECU reset. A couple of bimbles up and down the road and it holds stoich beautifully when pootling and dips to about 11 under boost.

Standalones are great if they're set up well and nothing is touched once they're mapped. As an old fud, I'm comforted by the fact that the ECU is sitting there fine-tuning a crude map and watching knock etc. 

I'm similarly fuddy about boost control. A manual valve and decent gauges sits better with me than a sensor & solenoid. EBC is great when it works but absolutely disastrous when it doesn't.
