ok guys i've got an xf throttle body on my plenum with the auto rb30 TPS (yes i've done the metal plate mod) when the throttle is wide open it isn't getting 100% reading on my hand controller. when its closed it reads around 2-4 when wide open only goes to around 31. i've even tried adjusting the TPS by undoing the screws & moving it in different positions but still wont get a good reading... kinda seem like the D shaft from the throttle body that spins the TPS to give the reading isn't spinning round enough...

could i have the wrong xf throttle body?

cheers

If you have a greddy mani, a vh45 90mm tb bolts straight on.

You can bolt the stock tps to it aswell.

J.

i was just looking at some of them. i dont have a greddy mani tho. does the fx throttle body have the same 4 bolt pattern on each of them???

Ok I've put my mates stock rb30 throttle body & tps on to check if it's works correctly but when i set the tps to 0 then open the throttle fully it's only reading up to 50% on my wolf hand controller. Is there any way to set 0 when it shut then 100 when it's WOT full throttle??? Because I can't think of anything else to do...

Yeah as guilt just posted you need to calibrate the tps travel and voltage to the ecu's end points.

So pretty much my tuner hasn't set it right from the start when I got it tuned yeah?

I called them last week & they said I need to get the tps working correctly before they can tune it, but it's never worked right after I got it tuned anyways...

Can they defiantly calibrate it via the ecu? In other words set 0 then 100 yeah???

Cheers guys

Yes you can set the limits in the ECU, eg flatten the accelerator and see what volts it gives, this is your max volts, then close the throttle and see what the volts are, this is your min voltage eg your limits. Should be very easy to do this.

    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
    • Yes sir am asking is there possible way from aem tuner from wiring pins 
    • Have you checked cam to crank timing and confirmed balancer marks are correct?
