100 PSI Boost into ECM feed.
- Thread starter McRat
- Start date
There might be an unexpected problem running this way. But it did record true boost at the track. I took some pics and will post shortly.
I'm not sure if rescaling the sensor so high didn't cause a problem. I'm 90% sure it wasn't blame, but I need to make sure.
Could be the tables can't handle the bigger number. That is, the boost values are probably out of range for tables that use boost as an index.
You would be safer to do a fake out by scaling it by 1/3. That is 100 PSI on the boost sensor registers as 30 for instance. That would at least assure yourself that you do not over run the index limits of the tables.

Sorry, I was busy doing an EFILive class. Yes, the first thing I have to do this week is to finish this testing up and write up the tutorial.
Here's the Honeywell P/N, and a picture of it with a MAP sensor end soldered onto it.
The Honeywell unit will read .5v at atmospheric, and 4.5v at 100psig. You will want to verify this yourself jic. You will scale B0202 to match this. Don't worry about the 72.5psi cap, it will have no effect.
I will get back to testing this more, but for now I got to move to other stuff.

Is that MLH100PGL05A? I might be blind, but I'm having a hard time reading the whole number.
