Have a scenario that requires expertise advise

[Cyrperformance]

OKPA, KOEO, bump starter and 50.2KPA

[Cyrperformance]

0kpa KOEO, bump starter 50.2kpa

OKPA, KOEO, bump starter and 50.2KPA

Put the key to on and start your scanner...thats all. what does the map say?

[Cyrperformance]

0kpa

[mowton]

thats wrong....you can change the data but assume it will be wrong also. Sounds like a wiring issue. Do you have the stock map sensor you can try using its values?

[Cyrperformance]

With the stock sensor plugged in it reads 50.2, I didn't change any settings just plugged it in.

[Cyrperformance]

Guess we will have to push 30lbs of boost to justify this sensor!

[mowton]

no settings are like 94.43 and 10.33

[Cyrperformance]

So change them load in and re read

[mowton]

yes

[Cyrperformance]

So added the SAE MAP and it reads 101kpa KOEO no bump.

[Cyrperformance]

If that is a three bar map wouldn't I need to go to the three bar OS in order for everything to read correctly?

That reading is absolutely correct so it says there is somthing going on with that map sensor. It may have said that it needed 10v reference so it may not be compatible with your 5v reference setup. I would try and get the sensor I recommended.

No, it just only gives you 2 bar of range. The values you put in the MAP sensor tables will align the pcm to the correct map reading.

You can continue tuning at least in the NA region with the stock 1 bar or figure out what is wrong with the unit/wiring you had in originally. Now you can go back and start the idle tasks over again.

Explain something quick, With the 366.7 and 33.33 settings loaded in the scanner it shows 105kpa in the SAE MAP but 0 in the 2bar MAP, why?

[mowton]

When you gave me the 1 bar map sensor reading of 101, was that from the 1 bar or 2 bar map pid?

Ed M

[Cyrperformance]

SAE MAP PID, which reads 105kpa with the 3bar sensor.

[Cyrperformance]

Here is a quick nothing running log with the 3bar sensor in.

[mowton]

Now I'm confused.....delete the MAP SAE PID and insert the MAP 2 bar. Save the configuration. Now tell me what the 1 bar sensor and 3 bar sensors read with KOEO with their appropriate MAP sensor data in the tune file.

I do need to run an errand at this point, sorry.

Its no problem, I really appreciate the help.
