Does anyone have a PSI vs voltage chart for this sensor? What boost ranges is it good for (limited by voltage range, not what the ECU likes) ?

Thats a standard 1 bar GM sensor, so it wont read any boost, but this sounds like what you are looking for:
Thanks! So I guess a 2bar sensor would just be the same scaled over 2bar. For which car should I ask for a MAP sensor if I want a GM 2bar?

you do realise that you cant just plug it in and have a 2 bar....right??
here is the chart for a 2 bar:
Manifold Pressure
(relative sea level / absolute) 2 Bar
MAP Output
14.31psi / 29.01psi 4.90V
14.00psi / 28.70psi 4.84V
13.00psi / 27.70psi 4.67V
12.00psi / 26.70psi 4.50V
11.00psi / 25.70psi 4.33V
10.00psi / 24.70psi 4.16V
9.00psi / 23.70psi 3.99V
8.00psi / 22.70psi 3.82V
6.00psi / 20.70psi 3.47V
4.00psi / 18.70psi 3.13V
2.00psi / 16.70psi 2.79V
0.00psi / 14.70psi 2.45V
5.00inHg / 12.24psi 2.03V
10.00inHg / 9.78psi 1.61V
15.00inHg / 7.33psi 1.19V
20.00inHg / 4.87psi 0.77V
25.00inHg / 2.41psi 0.35V
29.10inHg / 0.40psi 0.02V
Does it mount the same way and have the same pinout? If so, I can take it from there. I'm intercepting the signal line with my own circuitry and sending the ECU a clipped and scaled signal. I'll need the proper 2bar reading for driving the injectors though.

Oh also, if I walk into Pep Boys, what car do I say I want the sensor for?

dont walk into pepboys.....order from GMpartsdirect.com
they have one that will fit in the stock location, and take the stock pigtail.
search this forum, the part numbers floating around, I forget what it is off hand though.

Injectors are only referenced by MAP at idle.. Why don't you just use the LD9 SC reflash as it works on the 2000+ LN2 ? I have 2 LN2's running off it now.
