Target boost, fuel cut, MAP voltages...
I'm in need of some info.
Firstly, what are the target boost and the fuel cut levels for a standard UK '97? I seem to get about 1 bar peak and 0.9 held on the std boost control. Using a GBE to raise the boost, fuel cut seems to be just a touch over 1.1 bar, although I can't get it to hold more than maybe 1.05 - 1.07 without it hitting the cut sometimes. Secondly, does anyone have any info on the expected MAP sensor output voltages / maximum pressure etc ? Thanks for any help. |
Target and Fuel cut sound about right for that ECU.
The Map Sensor is as follows Bar Map sensor output (volts) 0.0 2.29 0.1 2.44 0.2 2.58 0.3 2.73 0.4 2.90 0.5 3.03 0.6 3.18 0.7 3.33 0.8 3.47 0.9 3.63 1.0 3.78 1.1 3.92 1.2 4.07 1.25 4.13 1.3 4.21 1.4 4.36 1.5 4.52 1.6 4.67 1.7 4.81 1.8 4.93 1.9 5.01 2.0 5.01 |
You're a star, thanks !!

Fuel cut on my MY98 was around 1.25bar (it isn't a single fixed value), are you judging it from a boost guage? I ran mine at 1.15 bar for about 2 years with no problem.
