Nistune

[chrisR34GTT]

Wondering if any Townsville peeps know of any local tuners that deal with NIStune? And by that I mean quality tuners (not Xtreme :s)... Sucks being regional, we miss out on top tuners that you metro guys take for granted. Maybe I should take a trip down to EFI on the Goldy??

[Haines]

Im in townsville and I run Nistune

Pm if you want

i can let you know who tuned mine

etc

ive got a nistune board in my 32. the car was runny very rich, and sloppy before the nistune (fmic, full exhaust, splitfires, 14psi blah blah blah) cold starts were shit, and it idled like a dog until the engine was hot, now with the tune, installed and tuned by mercury motorsports in brizzy, power is more apparent thru the whole rev range, idle is very smooth, better fuel economy, gained about 10kw at the wheels, but its just a nicer car to drive. i would deffinately recommend this product, as it does such a great job, easy to tune, and very reasonably priced. adam

Good to see my old thread alive and kicking still. Im on my 3rd Nistune board now. Using an Rb20 ecu to run my rb25 starts fine drives ok just need to tune her now.

Direct bolt on no stuffing with wires i just need to hook up a vct controller now

Recommend you look into some sort of device to read the revs and turn the VCT on and off, will add performance all through the midrange. I will be working on a product to do this exact thing in the coming weeks/month, but there are already devices out there that will do this.

Im looking at using an atmega chip to do it.

Should be to hard to count rpm and output a signal

Im doing the same with with a PIC (very similar to an AVR) you can get chips that convert a frequency signal into an analog voltage, will save you doing the counting in software and can just read the voltage with an AD module, might make it a bit simpler, that's how I plan to do it.

Care to share any details on this chip?

i dont know much about how the vct but just thought u could maybe hook a shift light up to it as in u could adjust the shift light to light up at 4500rpm or whatever revs you want the vct to turn on at, then just remove the bulb and hook the + and - terminals from the shift light bulb to the vct,

depending on voltage requirements for the vct and how its set up it could in theory work

I doubt the shift light would beable to supply the power requirements of the VCT solenoid by itself, but if you hooked it up with a transistor and relay it should work.

You can buy purpose built frequency-voltage conversion IC's. Alot of the manufacturers will send samples (saving you having to order 100 at a time).

doesn't VCT work by grounding

and doesnt it turn off in the higher revs

my knowledge is limited here

Yes the VCT should be turned on from 1500-5000rpm, if you leave it on in high revs you will LOSE power not gain it. We are advancing the intake cam here.

Using a shift light would be too slow an inaccurate, the easiest way to do it is with a small microprocessor. When I have time after uni, only a few weeks away I will be working on something which I will make available to people for this purpose.

A relay would be far too slow to turn on and off at the speeds we need, you need to use a FET.

You would use two and set them up for the lower and upper rev limits and use two ADC channels on the PIC, I think this would be the simplest way to do it. I haven't looked at the datasheet in detail but it should be sufficient for the 10hz-8000hz signal we will be seeing.

Does anyone know if the tacho signal is a square wave or a sine wave?

Will the Nistune have to be tuned after i get the Cam Gears put in?

Not necessarily, though helps to have the car on the dyno and adjusting them there and then to see if the adjustments made any difference or made things worse.

saves starting a new thread,

just about to either get a ecu remap from Ceff1e or DrDrift.

i live in adelaide so there in melb but is it ok to get a remap mailed out?

can the remaps be re-tuned after like a pfc? or do they need a whole new remap?

i would love to get my car over to vic for them to tune but this is not going to happen, well not for now.

so would i be safe to get them to remap and send me out my ecu?

cheers

Do you know NISTUNE is Adelaide based? Speak to Pete or Matt they could direct you to a recommended shop there.

[rad100]

didnt know that,

i know boostworx here in adelaide do them.

but i have herd the best things about DrDrift.

can they be re tuned?

coz paying $600 everytime i change a mod on my car is abit hefty.

otherwise i was thinking microtech.

do yourself a favor and call nistune, the ecu if it is a nistune remap can be retuned infinitely. We charge an upfront tuning fee then charge by the hour for retunes later on. Sam is very good at remapping and we send alot of westside (melbourne) enquiries to him.

Forget the microtech, adaptronic would be money better spent.

will do thanks heaps mate,

got a contact number?
