loaded question but - does anyone think this would be a good platform to learn how to tune with?
It's extremely easy vs trying to learn on stock ECUs etc. Remember these are made in the aftermarket for the purpose of easy tuning for the end user. When you're tuning a stock ECU you're using 3rd party software and "hacks" to get into the OEM ECU that they never intended anyone to be inside of and manipulate it to do what you want. On the flip side aftermarket stand alone ECUs are designed with a logical layout that makes sense and ease of understanding.
Yes you can DD on MS3 just fine but be aware it's not emissions friendly. No EGR control, rear O2 sensors etc. if that applies to your application.
It becomes better than stock when you hit stock ECU limits such as RPM or when you need additional features like flex fuel, WOT closed loop operation etc. that the stock ECU cannot do.
does this cause any problems with the Evap stuff?
Any idea if ABS still works?
I've seen these two items mentioned but no answer thus far
Regular MS3 does not support EVAP. I've installed regular MS3 units and PNP for other model cars and there is no support. It's not even in the software as a grey'd out option available for certain models etc. I have not played with the 03/04 Cobra PNP unit as that was just released but I highly doubt evap control is in there. On my car I have both the stock ECU and MS3 wired in at the same time sharing various controls so my evap is still operated by the stock ECU.
ABS has its own controller and should still work as normal.
Since the ABS is a separate module I would think it'll work fine. It's not connected to the ECU. At least that's what I was told when I inquired about using the factory wheel sensors for traction control.
That is suppose to be the passenger side kick panel. I had gotten the question does it fit behind the stock kick panel and that was suppose to be the picture of it tucked back in the stock location. I just did not take a good pic.
I am learning haha! I am taking it slow so far.
Main reason I got it. Plus I am an IT/I&C Engineer so I like these Techy things.
Wideband Sensor Addition
If a wideband Oxygen sensor is to be installed, its signal can be wired into the original O2 sensor wiring in the OE harness or to the EGO pin on the rear options connector. If the options connector is to be used, ensure that the OE narrowband sensors are disconnected.
Attachments
The wideband stuff is what has me lost. I'm interpreting it as I can use my existing AEM fail safe but I have to wire into the o2 sensor in the bung?
Cool, so unplug narrow bands and wire into rear of ecm to avoid messing with the stock ecm wiring.
Yes that's one option. I haven't seen the back plug on a terminator PNP yet but on the GT version they released right prior it only had provisions for a single wideband.
However you could always just get some old O2 sensors. Cut the harness off and wire into your wideband controller and then just plug it right into the factory harness like how a stock O2 narrow band would plug in. Boom dual (or single) widebands and no cutting of the factory harness which I know you hate.
Isn't there another input plug on the ECU? Like an expansion port kind of. If so can you connect the widebands through there?
I did have the thought of using plugs from a couple of old sensors so I could plug into the stock harness though.
There is. But not sure if it had dual wideband support. The GT version just released prior only had provisions for a single wideband on the auxiliary plug. Hence my comment to use the factory narrow band plugs as an option.
Genius! Now after i heal from my 4k livernois wound I may have to order one from you.
Psh. Its just a few more dollars. Plus it makes more sense to just put it all together now......
got a point there by putting all together now while it's apart
Lol it's just another can of worms. Then aeroforce doesn't work so then I need a new gauge. My wideband will work but not perfectly so there's a set of dual widebands.
It's my job to push Malcolm into buying more....apparently you ve taken it upon yourself to push me, lol.
Just sickening because I easily have $2500 tied up in tuning hardware that I wish I would have just put into a ms3 pnp. Sigh..
