what can tell me if i have a standard map sensor or 3bar? Its only stage 1 but would still like to check as boost is now about 15psi

 

Stage 1 generally a std map sensor.

Remove it and check the part number. I can't remember which way round it is but iirc the part number for a 3 bar is **/05

 

do i need to remove it to see part number as im sure its mounted on the inner wing or is it on side that cant be seen? Cheers

 

It should be mounted to the inner wing. To the left of the header tank, upside down. 3 x 10mm bolts hold it in. I'd say yes to see part number. But if you know who's chip it is. Just give them a shout and ask if they fit a 3 bar. I very much doubt it.

95% sure it'll be standard

 

cheers geeze. Not sure who's chip it all is.


How much is a new genuine weber 3bar?

 

Pretty sure the genuine weber 3 bars have a grey top and the standard ones are black. But as AJC says, best to check the part number to be 100%.

 

yer mine is all black i think and looks 23yrs old

As my boost is now over 15psi i need to upgrade

 

This sounds dangerous!

I assume your boost has been adjusted?

If so then there is far more involved than just changing the MAP sensor, namely a remap and injector changes etc.

Going by what you have said you may be heading for an engine meltdown!

hi martin. I put a post up about it a while ago which u commented on. There was no pre load on actuator and i was down on power. Just need a new chip to take into abount voltage chance between standard map and 3 bar one iirc. Injector are still within safe limits

 

Oh right, tbh it's going to be more a custom chip as typical stage 1 uses standard hardware.

Yes different map sensors have completely different scales so you would need a chip calibrated for it as such AND for the amount of boost you are running.

are 4x4 and 2wd map sensors different? i've read the wiring is different as the 2 end pins are the other way round? if thats the case can i swap them round and use a 2wd map sensor on a 4wd?

cheers

 

No. There the same. It's the tps that's different
