lack of knock sensor on 5S-FE Options

[Smaay]

so those of you with 5S-FTE's how do you monitor knock while tuning and every day driving?

[Batman722]

all 94-99 5sfes have a knock sensor
the earlier 5s (5th gen) do not

ah good to know, thanks

OK Batman but can the 94-95's [OBD-I] pull timing back to correct for knock the way the OBD-II's do?
this is relavent to a 5S-FTE I'm assisting with the build on. My old OBD-II Celica did of course and I'm hoping this OBD-I car will as well. I know it's no substitute for a good tune but it's nice as a backup.

Has nothing to do with OBDI or II.
If it has a knock sensor it can [and will] pull timing if it senses knock.
That's the purpose of the sensor.

5th Gens do also.
92 and later 5SFEs have a knock sensor.

Thanks Alltracman. I was aware that OBD had nothing to do with it but I did know that the ECU's handle timing differently [Try changing your base timing on both and keep the light on for a few minutes afterwards and you will see what I mean] so I wasn't sure if it was within the capabilities of the older ECUs.
Makes sense tho - what would it need the knock sensor for if it had no way to use it's output.

[alltracman78]

OBDII won't let you change your base timing, it will adjust back because it has a crank sensor.

I knew you knew that But I was just explaining my reason for double checking.

more good info, hopefully my little project will go smooth
