I was wondering if the denso 3 bar map was a plug n play replacement with no further modification or PFC alterations like the Gm 3 bar sensor? Or does the denso unit have to use the datalogit to program it in the PFC like the Gm sensor does?

 

Use Wargasm's calculator to establish scale and offset for your setup.
Leave the standard value and GM value in other options in case you go back to them.
I checked a new option 2 for my Denso with 46000 scale and 3200 offset.

I am going to install a 3 bar GM sensor as part of my single turbo conversion. If I change to Option 1, will that give me close to the correct scale?

 

no

 

My car was running great with the stock twin and stock injectors. I had tweaked the PFC and everything was fine. I am worried about changing to many things at one time. Do you think I should just stay with the stock map sensor for now and get everything running well with the larger injectors. Then remap later. I am planning to run 15PSI on a GT35R and was only going to run more boost later after I got the AI installed. The injectors I am installing are ID 725s and ID 2000s. I have the GM Map sensor from Banzai racing.

 

personally I would install the MAP sensor at the same time as the injectors because your tune will be messed up by the injectors anyway. However if you are not very experienced with tuning then you could do it in two steps, but you are creating more work for yourself.
