Gpro Posted September 16, 2013 Share Posted September 16, 2013 Has anyone used this or something similar to detect knock does it actually work? I can't detect knock with my piggy back so looking in to getting this http://www.ebay.co.uk/itm/Turbo-Cars-Knock-Det-Alarm-Engine-Detonation-Detector-Visual-LED-Alarm-/190890504688?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item2c71f5f1f0 Quote Link to comment Share on other sites More sharing options...

Gpro Posted September 16, 2013 Author Share Posted September 16, 2013 (edited) yeah i know but i still want to be able to log it myself (Could i just tap in to the knock sensor wires going to the stock ecu and have an led wired in would that work? I will be mapping the timing soon as i see the stock ecu retard then i will pull a few degrees timing but how much can i trust the stock ecu and knock sensors?

Wez Posted September 16, 2013 Share Posted September 16, 2013 If your mapping timing you should be using knock cans, not trying to spot a blinking LED. Considering some of the setups to come through here over the years I would say the knock detection / safety on the stock ECU is a testament to Toyota`s engineering department Quote Link to comment Share on other sites More sharing options...
Gpro Posted September 16, 2013 Author Share Posted September 16, 2013 would it be stupid to copy my friends map but retard timing by 4 degrees? to be on the safe side, i aint planning on getting every bhp i can get on a piggyback (His turbo is slightly bigger then mine and has a flown head, Everything else is the same) Quote Link to comment Share on other sites More sharing options...

Tricky-Ricky Posted September 16, 2013 Share Posted September 16, 2013 Why buy an over priced piece of tat, it doesn't even say what frequency its tuned to, different capacity motors need different frequency, so I doubt its accurate, if you want a decent knock sensor setup buy Phormula KS4, but in any case if your fiddling with the timing then always use det cans, there easy enough to make. What piggyback are you using? Quote Link to comment Share on other sites More sharing options...
Gpro Posted September 16, 2013 Author Share Posted September 16, 2013 (edited) Phormula KS3 analyser for £290 aint too bad, may consider that option as i don't trust an ecu made in 1993 Edited September 16, 2013 by Gpro (see edit history) Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted September 16, 2013 Share Posted September 16, 2013 So what make/model of piggyback is it? Quote Link to comment Share on other sites More sharing options...

Tricky-Ricky Posted September 16, 2013 Share Posted September 16, 2013 emanage ultimate You can set up the EMU to read and log knock from the std sensor in the channel setup. Quote Link to comment Share on other sites More sharing options...
Gpro Posted September 16, 2013 Author Share Posted September 16, 2013 yeah i am aware of that i will be doing that tomorrow until i get the phormula knock analyses. Just to confirm i use the intake temp wire coming of the emanage and tap in to 1 of the knock sensors on the stock ecu Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted September 16, 2013 Share Posted September 16, 2013 (edited) If you happen to be using the innovate wideband setup, you can also use this to datalog from the std knock sensor.

Gpro Posted September 16, 2013 Author Share Posted September 16, 2013 i got the AEM wideband. thank you will give it a go and see what it reads. thanks for your help Quote Link to comment Share on other sites More sharing options...
Wez Posted September 17, 2013 Share Posted September 17, 2013 i don't trust an ecu made in 1993 Are you referring to the original Toyota 2JZ-GTE ECU that had thousands of R&D spent on it compared to a an el cheapo piggy back with no R&D on said engine Quote Link to comment Share on other sites More sharing options...
