HKS quote...

The HKS A/F Knock Amp with its built-in digital display and face mounted controls is deal for high performance engine tuning. This wide band Air/Fuel monitoring device offers visual and audible warnings for precision tuning.

Has anyone seen these things work, or are they still too new to thge market. Price is about AUS$1,000.00

If i read right they are claiming wide band lambda which would make the unit quite cheap compred to thise from Motec etc

The SAFC II has a knock sensor output, would be alot cheaper, and with more functions, but probably not as accurate. I'm not sure how useful this really is, as once you car is tuned properly there should be little need to mess with A/F ratio's, unless your tuning it yourself.

See'ya:burnout:

Yeh im looking at wiring up my new ECU myself, and tuning it myself, and if as accurate as Motec/Microtech/Autronic lambdas then its almost half the price, and has in built alarms, so cant really expect it to come down in price too much.

Im going to be going to the next Motec seminar to learn the basics of ECU mapping, as at them moment my only experience is with my old MT8 which someone originally setup for me.

As i understand it the HKS unit monitors A/F ratios to control detonation, where as other units like the SAFC use a piesomteric (spelling... i know what i mean:D ) to listen for knock, often being sensitive or highly dependent on installation for credibility of results. I havent used one so that a pretty big assumption and someone please correct me if wrong.

My nature is that i never leave things alone for too long, and once i have the basic engine setup, looking to evaluate different setups at different times. If i cant do the tuning myslef this will soon get very expensive.

Also i like the idea of an an alarm as if im doing a 20-30 min session at the track, and say my fuel pump drops rail pressure, or an injector starts playing up, or my boost controller sends boost to 40psi (loose vacuum line) then the HKS unit becomes cheap insurance for my engine

    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
