HKS Knock Amp

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

Ok so this is an A/F meter with knock control is that right?

Knock control or just a reading?

Sounds good, price still needs to come down tho!

Does it use an extra exhaust sensor?

cheers

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.

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

Roy,

If your into serious track work then don't bother messing with anything like the SAFC, go straight for the good, and unfortunately, expensive gear. You need to be sure that the unit is working, so spend the extra money.
