PTUNING: Haltech Standalone ECU (Screen Shots pg. 5).....
As some of you may know, we've been looking into working with an engine management system manufacturer to help develop a standalone system for the tC for some time now. We wanted to go with a system that would meet several criteria - cost, functionality, and most importantly.....awesome software. 
Well as a tuner, I can tell you that I'm extremely exited about the results of our 3- straight, 12-hour days of testing and tuning on the dyno (I don't even want to see our next electricity bill,
).
If everything goes as planned, we will debut the prototype ECU set-up at the Redline Time Attack this weekend in Nashville, TN.
I'll get started by listing just a few of the many features of this fully equipped ECU:
- Runs as a parallel standalone with the DBW, cold start idle-up, and AC request controlled by the factory ECU.
- Will include PnP Harness with the most popular inputs/outputs terminated in a connector plug for ease of upgrading (i.e. boost control solenoid, etc) without rewiring.
- All timing and fuel is 100% under the control of this unit.
- CAN Bus output. Can connect to an aftermarket digital dash with just a few wires (CAN Protocol) rather than a huge mess of wires.
- Full VVTi control.
- Very, very high resolution mapping. User configurable.
- Has two sets of built in drivers. This means it can control both high and low impedance injectors and is software selectable - no need to fiddle with jumper switches. The low impedance injector driver is of the true peak and hold variety and not a simple resistor box.
- Built in 22 psi map sensor. Unit can also run any outboard MAP sensor up to 90 psi.
- Wideband input with closed-loop and target AFR autotune feature.
- Unit has the ability to switch between 2 onboard maps (i.e. street, race tune) with the addition of a simple selector switch.
- Launch control and anti-lag.
- Can operate to 16K rpms.
- Cost start and transient enrichment maps.
- Soft-cut and hard-cut rev limiters. Soft cut is ridiculously smooth and not a standard ignition or fuel cut rev limiter.
- Boost control via open loop or closed-loop PID control. Can set gear ratios into the software for gear dependent boost control - very useful, particularly on traction limited FWD cars).
- Overboost fuel cut.
- Full onboard or PC datalogging capabilities.
- Free software updates.
- USB interface with PC. No serial to USB adapters required.
We'll try and release more information in the next week or so, hopefully with additional information gathered from our Time Attack tC race car too.
Update: (09/01/09)
The Haltech ECU performed flawlessly during our Practice Session at CMP. We were running about 24 psi boost. The Haltech unit was controlling an electronic boost controller and was set-up for boost by gear to help with traction issues.
This past weekend at the E-Town Redline Time Attack event, the Haltech ECU was also in control of the stock motor set-up that we were running for the event. The unit again performed perfectly and allowed us to capture our third first place finish for the season.
We'll be updating this thread soon with screen shots, availability, final pricing, etc.

i second that idea......he can be the pro tuner.....and i can be the average joe tuner

We will fine tune the VVTi maps to optimize power and turbo spool-up on our TA tC. As with most race teams everything is coming down to the wire. Our new race motor coming together as we speak. We'll be setting the car up for boost by gear to help with traction issues in 1-3rd gear as well as limiting the power in fourth to avoid breaking that gear again. We'll be running full boost in fifth gear.
Anyways, our tC will be back on the dyno in the next two days. BTW, did I already mention that the software kicks a$$.

damn Toan, you announce this after I am finally happy with the tune you did for me on my FIC, rarely stalls out on me and no more sputtering haha... oh well after I get together the next mods I need, another trip from NY to VA for the ECU + tune is in order!

Ok, back on topic:
- CAN Bus output. Can connect to an aftermarket digital dash with just a few wires (CAN Protocol) rather than a huge mess of wires.
Up until this point, to my knowledge only the Hydra was the only other unit with that feature. I'm LOVING it already. can you Say "AIM Dash kit feed by the PTuning ECU".
I just got off the phone with Brian, and he was mentioning that you guys will be showcasing the new unit. Tighty everything up, and get your butts down here....hehe. You probably won't read this until AFTER this weekend, but we are working out the logistics for the first come first serve paddock area. See you guys in Pit Lane.

I have been watching the progress on the Dezod unit, but I will be VERY interested to see how that unit compares to this one. Can't wait to see more details. More choices on an ECU is a win/win situation. It gives consumers more options and it forces manufacturers to make better products.
