2ZR Turbo Yaris

Thanks gents! It has been a challenge but for now, one that was worth it. Time will tell. LOL.

Leegamer, yes, the standalone is a very attractive option and actually I could have gotten a Haltech Elite 550 in the $800 - $900.00 range and I think it supports DBW. I have not yet done enough research on the unit to know definitively if I could maintain all of my other accessories/peripherals. Also, the TCM is built into the stock ECU as far as I know, so not sure what would be involved with that. The HUGE advantage, in my opinion, would the ability to control closed loop fueling.

Sadly for DBW you need a 1500 or above, looked into these too, but beyond my budget :(

You should look into ECUMaster, they make really well-featured units for some really good prices, there's a good chance I will be getting one of these.

Thanks! Yeah, the 1500 is getting up there. A serious amount of cash to drop for one part of build, for sure. I will definitely have a look at the ECUMaster.

I've been looking at their ECU's and they seem well priced.

Does anyone know if you can essentially run a non drive by wire standalone ECU while leaving the factory ECU only connected to the throttle and maf sensor?

My hvac is all gone and as far as I know the only thing I would need is the maf sensor reading for throttle control for the factory ECU to still work

I was wondering this precise thing this morning. It would be nice and a cost savings too probably. But, I'd hate to be the one to try it out. Lol. The ECUMaster Black looks like quite a feature-rich computer and for around a grand, not out of reach necessarily.

Right now my car is running great. I REALLY want closed loop fueling control, though.

I agree, I just checked out their website and they have an ecu that can control drive by wire. However I just realized that the stock ECU controls the rad fan as well on my car. I'd have to wire in a control for that if I wanted to fully scrap the factory ecu. Not something I necessarily feel I need to do right away although I dint think it would be a bad idea

I believe you could use one of the generic outputs and a relay to do a simple on/off control for the fans?
