Im starting to order parts for a Vortech build for my 2006 S2000. The car already has a flashpro. I will not be boosting more that 10psi in this car. WIll the stock MAP sensor that the car has be sufficient or should I just go ahead and purchase a 3bar map? What map would work well and be plug and play with the flashpro? Thanks in advance!

 

If you are sure you wont be going over 10 psi, then yes, the stock map sensor will be just fine.

 

Just had a strange experience with FlashPro. They don't let you use custom sensors and there are only 3 allowed in the settings.

Stock 1.7bar (10psi max)
Acura RDX 2.8bar (26psi max)
Hondata 4bar (40psi max)

I stick to my theory that no sensor is good at its extremities so if you're running close to 10psi, you never know when you will go to 10.5 psi and then what?

I went with the RDX sensor. It's $160 from the online parts dealer.

 

Get the 4-bar sensor. You'll get 10 additional columns to fine tuning your fuel/ign maps.

$119 from SOS. Compatible w/flashpro

How do you figure? You probably get more columns if you're running more boost (obviously) but for ~10psi average stock FI system, the lower bar sensors should be better.

 

This. Works flawlessly, plenty of room to grow.

 

When you set the Flashpro Calibration setting to a 4-bar sensor, you are allocated 10 columns of boost to tune. So you can ultimately have 1 psi increments of boost. Using the stock MAP, you only get 6 columns of boost (which is a coarser tune).

 

I just opened the FP manager to see what you're talking about.

If I set to "show all columns", it gives me 20 columns of boost maps no matter what sensor I choose. (maybe you picked "show boost" and it gave you only 6)

Am I doing it wrong?

If you always get 10 columns (the other 10 are for < 0), then a smaller bar sensor would allow for better tuning resolution IMO.

 

You're right on the first part. I was correlating the Show all Columns to the 4-Bar MAP for some reason.

Do you have supporting data that shows a 4-BAR sensor is less accurate in the <10PSI range compared to the stock unit?

 

^ I do not. But knowing a little about electronics, think about trying to sample 1.2v from something that has a range of say 1v to 2v vs. something of range 1v to 4v. Does that make sense? I may be wrong though.
