Swapping ECU's?

[rob323]

Dezod, a couple of quick ones for you if you can spare the time please.
Can you have full control over the variable cam timing?
Can you convert it to run on speed density or map sensed?
Assuming I run some nice large duration cams with bugger all vacuum at idle, is it capable of accommodating that?

By the way, these questions are all related to using it on an Echo, whether that makes things easier or harder, I don't know.

No control over VVT. To be honest, we offered it in the AEM EMS we did for the Scion tC. Most people did not take the cumbersome efforts of tuning it, so it was left by the way side. The ARP lets the stock control it, which works just fine as it does a good job (not the best) in controlling it.

WHY WOULD YOU WANT TO RUN SPEED DENSITY!?!?! You are out of your mind if you want to do this! Use the MAF as the APR was designed to do. The MAF is MUCH more accurate and provides baro change correct, temp and humidity correction all in one. With MAP (Speed density) you must do that on your own. Stick with the MAF, use it's accuracy and be done with it. (also, don't worry about maxing it out, if you do you can run a GM 650g/s^2 MAF with the APR or even twin MAFs!) Take the 3D modeling of air and enjoy.

As far as cams, we've done 264s on the 2AZ tC without issues at all. We are now about to do some 280/272s to see what's up. I would not be concerned with cams and this unit at all. We've even run 850cc injectors too. No problems there either.

Understandable, but I guess most people wouldn't have access to a free engine dyno .

A hang over from my Mitsubishi days I guess (ECMlink), but the reason for my question was because down the track I see itb's in my future. To run the maf, I'll need to build a plenum for them (which is probably what will happen anyway). It's good to know that I'm not stuck with the stock maf at least.

You are out of your mind if you want to do this!

I'm not going to debate that, afterall I did build an Echo rally car.

Please let me know how the 280's go. Does the lack of airflow across the maf at idle cause any problems or can that be compensated for?

Thanks for the replies Dezod.

Cheers,
Rob.

Dezod,

Great info as always and thanks for posting.

Is the APR actively being tested/configured for a Toyota Yaris at this time?

We have one just about ready, and are just waiting on payment from someone.

If there are any more questions on this wonderful unit, I will gladly answer them.

I'd be excited to see the dezod unit, especially since last month I was hearing about how it was never going to happen for the 1nz. I just hope this doesn't turn out like the bolt on turbo kit fiasco.

Well again, it all boils down to demand. A turbo kit (to do it right) encompasses a lot of cash outlay to put units on the shelf and such. Just to put the point home, if we had taken the same approach as we did with the tC kit, where we put 100 units of downpipes and intercoolerpipes on the shelf, we'd be up poop's creek in this market. The tC market embraced our enthusiasm and bought it all and then some many times over.

I guess the point I am driving at here is demand. There needs to be people wanting and buying a product for it to exist. It must be a profitable venture for a company to undertake the challenge.

The engine management deal, can be done on a one or two unit basis, therefore requires virtually minimal cash outlay therefore offering a better change of existence to the market.

Seems like it would make it easier for the people that just want to use only bolt os but want more power. If it makes it that easy to street tune (safely)

This unit allows for turbo, S/C and N/A tuning with no problems!

Update! We now have successfully gotten the APR unit running on a stock 2009 Yaris S. The unit will be available by special order for the Yaris. Please call us to order.

This sounds promising. What are the expected gains on a NA Yaris?

Contingent upon supporting mods, tuning and fuel chosen.

[tk-421]

Of course. I'm just looking for a ballpark figure here... TIA

I have seen gains on the 2AZ N/A with this unit tuned on cams, intake, header and exhaust of about 30whp.

I tried to make another thread about this unit and it's capabilities, however a moderator deleted it. So, I will entertain any and all questions here about it.

I just restored the thread. It was mistaken for a sales thread. Sorry about that.
