Ecutek Flash Tune Dyno Results

[The Max]

How much did you pay for EcuTek in Aus if you mind telling me? or pm whatever you prefer thanks

Tunehouse charged me $1700 for the tune. I have no idea how much of that was the license component.

Thought I'd post an update on this, as the one thing I had noticed about six months later was some detonation when driving out of a parking station at low RPM, high load (i.e. uphill).

I've rarely had any time to myself to drop in on these guys during the week but I took advantage of my work-from-home situation (I still hate you, CCP!) and drop it in to Tunehouse for another run.

There have been a number of improvements made in the software, which I neglected to ask but we're now up to version 11 (I presume we're talking about ECUtek, not the Nissan firmware). My instructions were clear - dial out the detonation even if it means losing response, torque, overall power, etc.

The motor was around 30,000kms old at the time of the initial tune, if I remember correctly. This tune was at around 60,000kms last week. Despite the low kms, it was suggested that the OEM spark plugs be replaced (they installed HKS M54XL Super Fire) and give the MAFs a clean while they're at it, so I ran along with that.

The torque has definitely been dialled out of the low RPM range with less aggressive timing, which is what I anticipated and so the response off the line at the lights isn't as snappy when light on the throttle. WOT response from a standstill is still reasonably aggressive. I actually appreciate that because I'm not jolting the car as often, which was an annoyance before no matter how lightly I would feather the accelerator. I'm sure my passengers will appreciate it all the more! Better yet, my VDC isn't triggering as aggressively as it used to either, despite my aged but not worn Pilot Sport 3 rubber on the rear. Overall, the car is still just as fun for me but now it's a little easier to tame.

Surprisingly, we gained a further 5kW and another 9Nm of peak torque since the last dyno tune six years ago. Still, even if I lost 5kW, I'd rather that to egg-shaped cylinders from all that detonation.

@The Max

Its interesting to see your figures to be honest. It makes me wonder a few things, my 5AT 370gt pulled 218rwkw with similar tq.
my friends with the same transmission was 217.5rwkw. (both Uprev)


Wonder if thats a tuner thing or ecutek.

 

** Both of ours stock pulled around 195rwkw on 2 separate dyno's.

Could be a number of factors but my concern was primarily not to be as aggressive on the timing to avoid the detonation, so it could well be that I lost performance in that area.

Maybe the difference in transmissions plays a part (as in greater inefficiency)? The only real way of being sure where the point of difference is would be to get back to basics, putting your engine and mine on an engine dyno first, to take the transmission out of the equation.

was that done in a different gear to previous run? asking as the diff ratio is way different,,,,

depends on teh correction factor use, these runs are with DIN70020 which is not as common, not sure how much of an impact that has on the output.

You know what? I never even paid any attention to that until you pointed it out! I have no idea how the Dynapack dyno works, in terms of how it works out the diff ratio, but it definitely raises an important question. Six years had passed since the last time it was dyno'ed and unless they do keep notes on exactly how the dyno was done on each occasion, it's likely that the method had changed for whatever reason.

Seems a bit high though, doesn't it?

Mines a V36 350GT VQ35HR with 5 A/T - 202kw using UpRev on Dynapack. 

Gear ratio i used was 3.692.
