Those of you with a SECS monitor, can you tell me what throttle reading you have with just the ignition on?

thanks

 

Hi there dave
have you tried ringing stu or kenny from msd they'll know what it should be reading

p.s. its darren here you sent the part number to me for the little fuse box on the battery, went to ford with it and they still F*%ŁING useless

 

0 dave

 

should be 0% if its not you need to adjust your TPS (fiddle job )
also i would check that TPS is 100% OK

 

Thanks guys, mine reads 25% ??

I've slackened the securing screws and pushed it fully home but it still reads 25%, its a brand new tps by the way?

 

is the butterfly open at all in the throttle body?

+ have you fitted the correct TPS for you car?

 

no surprises there then Darren

 

Deffo correct tps mate, dunno if the butterfly is open as i've not disconnected the boost hose, i'll have a look tonight.

 

dave yeah i know
they are trying to tell me now that due to the part number you gave me turning up no answers that the part must be part of a bigger part (yeah right)
So i asked
well why would it have a part number itself then and where the hell would the bigger part go
Answer i g

eerrre not sure

 

My monitor does exactly the same, and bought it new, about 18 months ago. Have tried what you have and was told it must be a problem with my loom. Still doing it now, just live with it now. Still annoying though.

 

My show 7%, i speak to Jens Hanestad (norwegian Cosworth guru) and he told me thats ok, he set it from 7-14%, its more important that it get 100 at full open

 

Is it true that you get a high idle speed if the value is too high? And if not speaking in % what should be the right voltage reading at idle?

 

the correct voltage as seen at the ecu for a 4x4 (PF09) TPS is between 0.25 and 0.3 volts or 250 to 300 millivolts depending what scale your autoranging meter selects you will find that this is almost exactlty half way along the elongated slots

 

dave, your TPS could be nakered, i have one brand new at home if you need one, drop us a call if you need it

 

Thanks, mine was 0.192 Volts with the old TPS and 0.135 Volts with the new TPS at the same 40 Ohms adjustment. (i thought this was the correct base setting for the tps..). Now I have adjust it to 0.306 Volts.

Also tried 0.385 Volts (thats a base setting of 70 Ohms someone advised) but then the idle speed rised towards 2000 rpm!!

So I hope this 0.3 Volts setting also cures the problem that I had for having to adjust my CO to 8.5% to get it drive smootly off boost. Hopefully it can be turned down now to the required 3% for a smooth drive.

 

cheers andy, if i could borrow yours for comparison it would be a big help

 

correct, to high a voltage back and the ecu kicks up to fast idle by opening the ISCV and leaving it open - been there - done that its all well and good setting it up for resistance at hte TPS, but its what the ecu actuallt sees back at the connector after its travveled down a scabby old ford loom that counts

 

Well thanks again hope it will solve the fueling problem.

 

Is this at idle or just with the ignition on ? Cheers
