as title

my rs turbo was cutting out when driving so i disconnected it and it dont cut out now can anyone help me

 

If you use boost without it, she may meltdown. Get her fixed

 

y would it be cutting out with it connected its doing my head in

 

sounds like its fecked mate, just so happens I have a spare one in my shed...

 

lol i need it asap an u in the iow

and im in kent lol

how could it be that both of mine r fecked

 

its basically a variable resistor that changes resistance as the throttle opens wider, the ECU needs this information to change the air/fuel mixture jus incase u didnt know

 

where can i get a new one then lol that works

 

Sorry, you are technically wrong

(if this RST S1/S2 car is running original KE jetronic system)

The tps on this car is only 2 micro switches. (you can hear them click)
So the fuel ecu, knows when idle or full load is being demanded.
It is NOT a variable resistor type as per cossie ... etc...

 

so with it not connected does it mean the fuel ecu thinks its on full load

would the problem be with my fuel ecu cos the problem has got worse over time

 

ok just burst my technical bubble

 

lol init good try mate any help here is better than wot i know cos if i knew id be happy lol

 

With it NOT connected, the FUEL ecu thinks you are in part load.
I.E Not idle and NOT full load.

On most ecu's, extra fuel is only added for high boost conditions when the throttle is fully opened.
Not having this extra enrichment particularly when tuned beyond its original power level,
the tuner may be relying on this enrichment to get the AFR correct so preventing melt down.

I may be wrong but to me, it sounds like you have other issues with the car and it may not be the TPS sensor !!

 

im only running 8psi at the mo need a chip but the engine is low comp and stage 3 head and piper 285t2 cam and im running a stage 1 2wd cossie turbo

wot else could it be it was doing it with my mates chipped ecu but not as bad since i had the fueling set up its doing it more

 

i'd get it set up on the RR to be sure then take ti from their!

 

ive got it booked in at the tuner near me dartford tunning people round my way have said there good all i want for the mo is for it to run rite then when i get it chipped i will venture up north to the big tuners lol

 

dave1982rst, If you have changed the engine spec but NOT the fuelling this
could be your problem. Too lean under load !
A chipped ignition ecu (silver box) will NOT adjust the fuelling !

As vroooom ptssssh, says get it checked out/set up properly -

 

would that make it cut out tho like it is

its doing it on normal driving not just on full load even pulling away like a grand dad taking my time it still does it

and i reved it on the spot up to 4k and let off the put throttle bk down and nothign till the revs died to 1k then it reved again

so it mite not be the tps sensor fecking up then
