I have a Nissan 240sx with an RB25DET. It has an AEM Stand alone EMS. I have had it lean under boost and never seen Knock...

I was wondering the procedure for testing the knock sensor circuit before I put in race gas and start adding timing.

Thanks

its an aem ems, series 2 for the r33 rb25. It has knock charts on the program on my laptop. it just always reads 0. Ill mess with it and see if I can get a fast stock turbo video up for you guys. I wish I was playing around at sea level!!!

Sorry here in AUS we have AEM stinger and motorsport ecu's which are different from the US based AEM version 2.. in fact they are not even similar. I JUST NOTICED your location is USA or similar.

The AEM Version 2 is an AWESOME ecu and we tune a fair few turbo hondas and some bigger hp supra stuff with them, YES it does have knock control and feedback engines but ive not had a play with one in a R33, it worked awesome on a turbo S2000 we did.

I have a feeling it wont be compatible with the std RB25 sensors, but send Aem an enquiry as to whether ot not they are supported as its a great feature in the Version II.

Yea it is definitely a very cool program. I have done all the tuning myself so far, just by data logging runs at the strip and third gear pulls. The weather is kinda shit right now. but I am very excited to see what this rb 25 has got in the future.

    • Yep that's pretty much what I want to see. Racecars that look and sound like the Group A but with newer tech underneath to make them faster and safer. I'm sure there's enough VK-to-VN commodore, E30 BMWs and Foxbody mustangs shells around to make up a decent number of cars with hopefully a couple of sierras, rx7 and R31s in there too. 
    • Contact Jessestreeter.com/Skevas Racing/JustJap for a new r34 rb gearbox or go a cd00# conversion. No point playing with unknown condition gearboxes.
    • Such a shame places like Amaroo Park have been redeveloped, smaller tracks always make for good racing. Cheers for sharing @PranK there's some good Lakeside video's too. Its so hard with older the cars as parts are so rare and everything was made for a particular chassis at that point in time. Even the V8 Supercar Blueprint era cars are all different between each chassis within a team as they learnt things and made improvements. The COTF cars between each Chassis builder is different too especially motor/oil systems/intakes. The Group A stuff is worth so much too especially chassis with good history. The only way to do it would be composite panels and similar engine drivelines to the original cars. Ford sierra running Focus RS driveline, Commodore running a short stroke LS/LT or a Falcon with coyote and a H Pattern dog box. Could use a standard ecu across all models with a Torque Map and DBW for parity which is not even used in Supercars currently. Hell a TCM is almost a full chassis car these days and the suspension is not even close to standard style in the front running cars.  
    • Dashcams Australia (13/05/25) captured JDMHSE (Vic plate) being a right tosser. 
    • Wish someone would start a racing series for Group A replica cars, a bit like Touring Car Masters but for 1985 onwards and not grandpa's falcon and/or Monaro. I know they race in some historic class but that's for original cars, no replicas allowed.
