**** happens, no one got hurt, guy got paid with-in 5 business days, I'm not legally involved in anything, it's a screwed up situation , I just roll my eyes when people talk about it. People make it seem its like something its not.

I haven't talked about it too much because there is currently legal action going on between other partys*. That's all I care to say on the subject

Fair enough. I would have chosen to express myself differently considering the situation and the publicity, but that's just me.

Found some really good logs..

I have a stock car logged, then my final tune which shows actual ignition timing, and what the car would have ran is EcuTek wasnt on it

Give me a min

Sh0velMan

Sounds good.

What about the boosted guy? Think Guise is running ecutek? Would like to hear ur opinion on how good ecutek works on boosted vq's

Well, I was expecting a CSV, but this does show 30 degrees being commanded and logged, which is a touch more than I've ever seen my own ECU do under any condition. (At WOT above 6k RPM)


Curious how your much more linear timing curve affects low/mid range response, but you can definitely tell the Nissan code isn't at work there.

Looks like you can definitely get 2-3 more degrees of timing with EcuTek than you can hope for with Uprev.

What you can take away from this is how inconsistent the factory timing control is on these cars.

Nothing has changed mechanically on the car yet the factory ecu runs a different timing curve almost every time I pull the car.

For those NA guys this might not be a big deal because it's not going to blow up your motor, but on forced induction guys that extra 2 degrees of timing the ecu *might* add could be a problem.

With the EcuTek's RaceRom ignition control we are able to bypass the OEM timing logic which is in calculated burn time with real ignition maps that do what we want all while keeping Knock Control

Just to be clear though, the parameter "Ignition Timing ()" is a MEASURED/OBSERVED reading, not a commanded reading, correct?

Just like I can log commanded AFR vs the actual observed AFR.

Curious, this is on the dyno, yes? Dynojet?

I've never logged on a Dynojet, only a Mustang and on the street, so the loads are a lot different. Just trying to reconcile what the stock ECU commanded there vs what mine commanded in the same conditions.

Correct, Ignition Timing is what the motor is actually seeing after air intake temp comps and knock control.. its the final value ran NOT commaned

EcuTek has some more advanced datalog parameters that can only be logged with one of their flashes. One of those parameters is Ignition Timing Calculated, which shows what the car would have ran if you were using OEM timing control.

Was on a mustang dyno

Wow interesting.

Never had my car (stock) do anything more than 27 degrees on the dyno, 24-26 was the norm.

Now I can expect 28 regularly depending on coolant temp, which is a lot more stable with the huge radiator.

Wonder if the G's huge front cooling surface area has anything to do with that.

Anyway, thanks for all the info.

This car was the strongest baseline I've ever had..

So yes, this car ran a few more degrees of timing than the others.. That's the thing, these cars have a dynamic timing control, it can switch between 3-4 different timing maps that have all these crazy multipliers.. You change one table and the car switches to another set of tables.. which is why the timing is often not the the same.

Different ECU versions have crazier timing control than others.
