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

Its a long story. John and I have had some struggles. Between **** breaking, being 4-5hours away, and some unfortunate life changes things have been moving slow. Im hoping to get back up there soon and get everything finalized. I just don't want to give my full review yet until then. Most of the slowness is just the fact Im custom. Were having to fix and change things that all of these other companies were able to do during the R&D phase.


John, if you still have it...Im sure these fellas would like to see my last dyno pull. I would've posted it but I left the print out at the garage.

I dont have it handy, I'll try to grab it next time I'm on the dyno.. maybe saturday

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

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.

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.

Told you to make that switch

Could u elaborate on what you mean by this? Are boosted guys gonna see gains or smoother n better drivability?

visconti

Boosted guys/gals are going to see a consistent timing curve, unless there is some kind of knock.

Take a look at the log i sent before, the cars timing curve is all over the place, even if you tune the car using OEM maps the car still has the control to change ignition timing for optimization.. which is meant for NA.

I personally rather have a car that has the same amount of power everytime I touch the gas

John

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.
