Sorry for the spelling mistake with your user name delco. It's been a while since since I've seen the car run, but I'll try & get him tomorrow depending on his kids sport.

Should the engine still run with a 2 bar sensor & a std ATFY chip?

nope

you need the get something like $12P which can handle having a 2/3bar map sensor plugged into it ... having said that you stilll need to let the tune know you have plugged it in.

there is also a $5D 2bar tune out there, but its not that good because it has alot less clarity in the ve/spark tables due to being a hacked 2bar file.

so i guess the short answer is, if you have put a 2bar map sensor on and your running atfy then thats probably why its not running!

well my map died over the last week or so its been cutting out and wont restart did it today hooked up laptop on the side of the road map sensor error i was about to swap fuel pumps LOL.so yes a dead 2bar will pretty much stop it running

can't say i've ever heard of a map sensor dying!

they ahve a tendancy to pop there lid mine is just like bad connection if it does it tomorrow on me ill throw in the spare i have in my pocket out the vb for testing

The map sensor is new & I'm just trying to test it to ensure it's ok. What do I do to a $12P tune to operate with a 2bar map & boost?

in the flags section there is options to tick/untick depending if you want 1 / 2 / 3 bar map sensor.



map a settings are the normal ones, only need map b if you have the map switch connected.

so you can see above, if you untick both selection A & B you have 1 bar, tick A and untick B you have 2 bar sensor, untick A and tick B and you have 3 bar!

I've been playing with the this car today. I've put it on petrol(so I don't waste alcy), fitted the 2 bar sensor & made a chip. This bin was the n/a methanol bin that was working ok with some changes for petrol. I can get it to fire & idle for a couple of seconds then it stops. It will run with the sensor hose disconnected. I also tried the "$12P - v1.04 - turbo vn v6 - 2bar base tune" but it tries to fire but not much else. Can someone please have a look at the bin for me & tell me were I'm going wrong. Thanks in advance.

havent looked at much else but you have got it set for 3 bar. you need to to have the first one ticked and the second one UNticked to set it to 2 bar.
