Great data...I hope to compare soon.
So, in your single gear pull, it looks like intake temps went from about 77-84F (7* rise) and in the multi-gear pull, they went from about 70-90F (20* rise). This will be great to see how an aftermarket IC compares. |
Very very cool stuff, mrfred.
Could this ADC be configured instead for pressure logging? I'm envisioning EBP sensor logging.... |

This ADC channel supplies +5 V power and has a 2.25 kohm internal resistor that runs in series with whatever resistance is in between the ADC pinout and sensor ground. The ADC signal represents the voltage across the resistance between the ADC pinout and sensor ground. I don't think it can do anything but measure voltage across the resistance. I'm not positive though on what cannot be done with it. Perhaps one of the electronics experts could comment?

How fortuitous, it just so happens that the Ford EBP sensor (p/n 8C3Z-9J460-A) is 0-5volt output. I don't want to hijack your thread with this, but it appears this ADC may have potential for all kinds of logging in addition to temperature.

any updates for a 94170015/14 map??
im about to go MAFT soon as well. |

I'll take care of this after I finish my front O2 sensor patch that's in the works.

I just ordered a GM IAT sensor. I am going to pull the mani off and tap it in the stock location. I can't wait to get this working so i can quantify improvements when i move to a new IC this winter.

I've been driving around for a few months now routinely logging MAT and IAT, and I'm finding that if I'm just cruising around town, MAT is almost exactly equal to IAT, so the notion of heat soak occuring during daily driving doesn't apply to Evos, at least for Evos using the stock IC.

mrfred, does that include creeping along in prolonged traffic?

Makes sense since you aren't cramming hot turbo air through the IC. ;)
Now try another test. Idle the car for a little bit, then go WOT. Then drive around 50mph or so then go WOT. Be interesting to see the delta in air temp increase between the two. I would imagine it would be better at 50mph than at 0mph as you have a bunch more airflow over the FMIC. |
