Power Fc Or Nistune

[ISC-Performance]

At the end of the day there both good options it just depends how much you want to spend? Keep in mind if you have any R32 rb20det you will need an ap engineering power fc and they are more rare and also more expensive. I have ran both and rate them both highly, the main upside is with the power fc you can monitor what your car is doing via the hand controller.

Does anyone want to make comment on the PFC prediliction to randomly "sneeze" because (AFAIK) of the way it reads the signal from the AFM's without much in the way of damping? Does the Nistune do this better?

I had a bit of a read last night about the knock control issue that was brought up above.

The knock control is used only in a thin band of load/RPM but it is selectable. By clicking on a load cell you can tell the ECU whether you want to have knock feedback in that part of the map or not.

Generally tuners turn it on through before and after peak torque as this is when you are encountering max VE (Volumetric Efficiency) and therefore you are getting the best cylinder filling and the highest cylinder pressures. So this band is where you will encounter knock. The knock feedback is turned off higher in the rev range to do the background noise being too great and giving false knocks, so you don't want knock control in this region anyway.

If running an RB25 you also need an external vct controller as the rb20 ecu will not do it.

A couple of years a go there was talk of re-tuning 33 ecus with a write-once chip, or having them permanently re-tunable via an emulator daughter board, but all talk on this seems to have gone quiet?

In stupid terms;

A tuner can set at what RPM your knock control is active. So you could set it at say 5,500-7,000rpm and it'll pick up all the knocking between those RPMs and counter it but do nothing at anything before that?

[D_Stirls]

yep it's up to the tuner what cells are activated for the knock feedback.

This will help i think;

This is the ignition Map for a Z32, the red squares are are where the ECU accepts knock feedback and the blue squares are where it doesn't, but the tuner can change the squares if they desire.

nick if u get a z32 ecu u can run vct!

[Luciano]

thats true^

boostworx supply the z32 ecu with nistune map for the 33 25det, and dyno + tune for approx $950. good deal imo.

[DSTROY]

Anyone know what the go is with Microtech's, my friend has one for sale and has a Plug to suit R32. Who can tune them and will it plug up to my ceffy?

[boostin32]

Don't get scared off a Nistune based on a "he said they said" basis. Call Nistune themselves and speak to the guys direct. Nistunes retain knock sensing throughout the rev range ... PFC will just flash a light at you.

no wories ill ill go down and speak to them

sorry guys but i have no idea what "knock" is haha ill look it up soon

my nistune runs my 360 rwkw stock internaled RB25 juuuust fine

[Luciano]

my cousin had his z32 ecu w nistune installed and tuned today at boostworx in his 33 gts4 rb25det. 60rwkw increase... unfknbelieveable!

it was running pretty average with the standard 33 ecu beforehand however.

but - nistune, quality. no doubt about it

[Volk34]

i ordered my nistune motherboard yesterday n getting it tuned and installed monday next week i cant use a PFC due to having an auto :'( but im pretty confident that this is going to suffice

[Luciano]

definitely another advantage being able to tune for Autos too; theres a good chunk of the tuning market for skylines that apexi wont see...

[Krishy]

with the nistunes are they reprogrammable or is it a once off tune sort of thing????

[Luciano]

reprogrammable Krish!

[Dohmar]

reprogrammable Krish!

and realtime too!

Why cant you program nistune on an auto? the automatic ecu is a separate unit to the engine ecu... mine used to be auto, i looked at both the auto ecu and manual one and they are exactly the same.

Anyways, bang for your buck, nistune.

pfc is a good ecu but knock function is a fairly big downfall. if you know how to adjust maps on the go then thats fine but what if you have no clue, get a bad batch of fuel and dont take notice of it till its too late? thats where nistune wins it for me.

as far as hand controller stuff goes, you can get a hand monitor for a nistune also. you cant change maps however you can see all the data like the pfc, and since the nistune adjusts map for knock etc you wont need the controller function anyways. There are plenty of nissan consult style hand monitors you can buy from j-land and locally too, shows you everything you need to know.

Also, r33 ecus, you can get an external emulator to run the system. afaik only person selling and tuning them is Sam (Dr. Drift) in VIC but im pretty sure you can just buy the emulator and get it tuned locally.
