supra matt Posted July 30, 2006 Share Posted July 30, 2006 hi all fitted this the other week and went to get it set up . But once i started to drive it hard it started detting badly! it was 28 deg outside so was it just to hot ? what knock levels are people using safc seeing ? might be worth checking before you drive hard in the heat. Anyone no what would of caused this? my car is tt running 1.2 bar with fmic , welbro , ik24 , and fillter fitted in wing so get's lots of cold air. Going to fit inlet temp gauge today to see what sort of temp the engine is taking in . Any one no what a good temp is ? thanks Link to comment Share on other sites More sharing options...
Guru Posted July 30, 2006 Share Posted July 30, 2006 You don't want anything over 60 really. You'd best figure it out quick! It won't be intake temp. What AFR reading do you get? Link to comment Share on other sites More sharing options...
JohnA Posted July 30, 2006 Share Posted July 30, 2006 The knock readings from SAFCII are not worth the paper they're written on Link to comment Share on other sites More sharing options...

supra matt Posted July 30, 2006 Author Share Posted July 30, 2006 The knock readings from SAFCII are not worth the paper they're written on the bloke who was setting it up had some det head phones on to . and the safc was showing big det in conjuction with what he could hear . So i just use it as a refrance now . any idea why it would be detting so much? Link to comment Share on other sites More sharing options...
JohnA Posted July 30, 2006 Share Posted July 30, 2006 the bloke who was setting it up had some det head phones on to .. Ah, that's better:d What sort of revs were you seeing this det? How much boost was it registering at the time? What sort of fuel have you got in there? Link to comment Share on other sites More sharing options...

Guru Posted July 30, 2006 Share Posted July 30, 2006 Yeah get back on Optimax if you can. How old are your spark plugs and fuel pump? Is it the standard ECU or other? Link to comment Share on other sites More sharing options...

JohnA Posted July 30, 2006 Share Posted July 30, 2006 Was the ECU fresh from a reset? It's important, because then it would be expected to hit detonation levels for a second or two. Second time round it's less likely and third time round it has learned the lesson. I'd get the injectors cleaned, just in case there is one blocked. Better be safe. Try the STP Total System Cleaner for starters - cheap (well, £15) and it might do the trick. Link to comment Share on other sites More sharing options...

Guru Posted July 30, 2006 Share Posted July 30, 2006 I wouldn't even boost at all if I were you mate. The slightest thing could end up costing £3k or more! Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted July 30, 2006 Share Posted July 30, 2006 Just a thought Matt, not having used the SAFC 2, but i presume it picks up one of the knock sensor feeds as it enters the ECU? are you sure you have the right wire? as a lot of those devices will register even if they are seeing a voltage rather than a frequency.

paul mac Posted July 30, 2006 Share Posted July 30, 2006 i run an safc and plumbed one of the knock sensors in i have never paid much attension to the reading as sometimes i get home and am getting a reading of 11 on idle !, however i do know what knock/det sounds like after being raised on 2 strokes, i used to get about 1/2 a second worth of knock on the 4000rpm change over point when i ran the stock twins, i never cured this and did not overly worry about it (it went away when i went single), your problem is knock at high rpm, make no mistake mate this is an engine killer YOU NEED TO GET IT SOUGHTED or you will pop the motor, dont try turning the hi-fi up this wont work either lol, you wont find any magic cures on this site you need to take the car to a pro Link to comment Share on other sites More sharing options...

Tricky-Ricky Posted July 30, 2006 Share Posted July 30, 2006 Yeah my car is fine now mate:) just waiting for EMU so i can get the fuelling spot on, i think the only way to be sure about det is to make yourself a set of det cans, and have a good listen, i do know that some of those devices are a bit over sensitive and do pick up other noise, especially valve noise, my Power FC used to see silly det readings on the S14 but i could never verify this with det cans, and it never went bang, but don't take any risks until you have a proper listen mate.
