lemmy01 Posted July 30, 2012 Report Share Posted July 30, 2012 My vi-pec map-sensor(2,5 bar) give up after 800 miles so i wire in a toyo Map-Sensor lying around in my garage. PartNr:89420-17040 its from a na Mr2 sw20. The st185/st205 calib do not fit. The Subaru EZ30 AVCS calib is the best i found in the list, the values at idle(27) and engine off 99 are ok but it seems the space between is not 100% correct. I get some lean cells at -60/-50 MGP that where correct with the vi-pec sensor. of course i did a calib with the new map sensor. Could someone provide a calib for the sensor.

trd87t Posted July 30, 2012 Report Share Posted July 30, 2012 I'll check my part number tonight and see. I doubt it's the same one as mine is from a 2JZ-TT. If it's the same, i'll post up my CAL Table tonight for you. Quote Link to comment Share on other sites More sharing options...

lemmy01 Posted July 31, 2012 Author Report Share Posted July 31, 2012 Thanks jason, but there is 17030 and 17050. I have 17040. I tryied the st185/st205 calib and there is a big diff to 17040 My sensor reads 195kpa boost with these calibs when it should show 100kpa Quote Link to comment Share on other sites More sharing options...
Jason Posted July 31, 2012 Report Share Posted July 31, 2012 sorry about that, doing a little more checking the 89420-17040 is from the naturally aspirated 3sge engine. Probably best to set it up on a bench with a vac tester and build your own calibration Quote Link to comment Share on other sites More sharing options...
gti1434501145 Posted August 1, 2012 Report Share Posted August 1, 2012 MAP sensors are usually linear. Check the voltage at 100 kpa. Put that in the calibration table. Then try different values at 0.5v so that the reading looks correct. Check with a hand vacuum pump with gauge. Quote Link to comment Share on other sites More sharing options...
