More Problems!!!
Well I got rid of the Typhoon intake and put on a ls6 intake. There were no sealing issues but just to be sure I did that for good measures. I also traded My 2 bar map for a 3 bar map. This is where the problem comes in.
And Yes it has a 3 bar tune on it for those that will ask!
I thought I traded with a pretty respectable FI guy here and until I talk to him I will Not mention any names. Car will not run at all with the 3 bar sensor plugged in. It starts for half a second and dies. No chance of it even running. So I turned up the fuel pressure to see if that helped nope. Got t up to 75 and nothing new.
Then I decided to plug in the 1 bar map to see if it would start. Much to my amazement the car started the first time. DId not run well by any means, so I turned down the fuel pressure the more I turned it down the better it ran was down to 9psi before it ran ok.
So in summary, map I got was bad now I do not even have a 2 bar map. I just want to try and finish this thing. Everyone that says that these projects will nickle and dime you..... Pfff they are not exaggerating.
So does anyone have a working 3 bar that they want to get rid of.

I had the same problem lately. I switched from a 1 bar to a 3 bar and the car did the same exact thing...ran for a second and then died. Would not run at all. I switched back and it works fine. I then hooked up my scantool and watched the map voltage with the 1 bar and it was fluctuating in the 2.5 range. I then redid the wiring a second time and tried the 3 bar again and the car only read around .5 range. I then switched back again and never tried it again because I was pissed. I am anxious to see if you actually got a bad sensor or if something else may be wrong. I still get a p0106 code pretty often, but once I clear it the car runs fine again. I haven't tried testing the voltages from the ground or reference wires. Good luck.

you cannot simply just swap out a 1 bar to a 2 or 3 bar and expect it to work. You will need to have someone with tuning solftware update the correct map values. Good luck!

Just thinking the same thing. I had to rewrite the entire operating software when I switched from the 1-bar to 2-bar setup. That's the main reason I still run a 2-bar....even though the car's NA now Same deal when going from a 2 to 3 bar.

Thanks very much, and I apologize I probably should have mentioned that. Speed inc did put a 3 bar tune on it already, I had a 2 bar map on it and it was not running well obviously.
I am going to check some values tomorrow with autotap and see if I can come up with anything but as of right now I have been told that this sensor absolutely worked. So tomorrow we will see what happens

It only runs if I put the fuel pressure down to 9psi. This is very similar to what I had to do with the 2 bar map in it. except it was at 28psi with the 2 bar in it.
Question would be why would giving less fuel make it run. I was having a conversation with cablebandit and he made a very valid point to me. Why would less fuel make it run better, as you change sensors and go up (1 bar to 2 bar and then to 3 bar) should you not have to add fuel or is this not correct!

Did yall ever figure out what was wrong? I had this same exact problem, car would crank up and instantly die but with the stock MAP at least run. Got a new MAP sensor under warranty & it did the same thing. I got on our alldata system at work and got the pinout for the stock map & realized that the the wiring harness adapter I bought had two wires in the wrong location. I pulled out the pins and swaped them around (the black & gray wires) and the car runs beautiful. Man I spent 2 days pulling my hair out trying to figure this out.

yup I had a similar issue. The sensor that I had to get was a universal it I guess. What way I thought was right was not. So I had to flip the sensor around. Oh my god started and ran a ton better. I feel bad because me and Cable spent probably 60 dollars in shipping because of the damn sensors
