Looks like he didnt read what you typed and jumped to a conclusion. Your both right.
I know i had to read your post twice just to make sure i wasnt reading it wrong.

I guess it depends on your definition of "high boost".
A 2 BAR MAP sensor will only read up to 14.7 PSIG. Some would call that high, while others such as myself do not.
BTW a 2 BAR+ MAP sensor is not nessisary, which is what I think syn was getting at. I have ran a few turbo and supercharged vehicles utilizing a 1 BAR MAP. There is just now ignition or fuel trim/enrichment in proportion to boost pressure.Comment

Actually, your post does sound confusing. It almost makes it sound as the 2-bar is what you want for high boost and the 1 bar is fine as long as you're running low boost. I too considered it wrong by looking at it.
Besides. I dont consider 15psi to be high boost. If you max out a 3-bar sensor (~29psi) then i'm sure that'll qualify as high.97 Cavalier RS

Since when can you used a 1bar MAP for boost?!1984 Indy Fiero 3.4L

I don't think it's really something that should be done unless you are hacking along the job. I myself even went to II-Bar to make life easier, & I am not the motivated type.Lifting my front wheels, one jack at a time.Comment

well i guess it depends on what your doing for fuel/spark that would depend on the map, if you use a rrfpr and ect and really no spark control you can keep the 1 bar map. but what i was saying is if the computer is going to be able to read boost you'll need a 2bar.
i actually read the post and didn't jump to a conclusion

If you don't mess with the PCM/ECM, I would think you'd have issues running pump fuel around the 7PSI + range. ??? Even if you do use all those other bandaid parts.Lifting my front wheels, one jack at a time.Comment

If you live at 6000'+ a 1 bar works pretty good up to a few PSI boost

15 psi can be high boost. It depends on the engine. If you got a 427 V8, 7 PSI is damn high. If you got a 2.0L. 15, not so high.

Care to explain the logic in that? How does the displacement of the engine have any effect on what is considered high and low boost?Comment
