Neon SRT-4 Setting up 3 bar map sensor

[evlgsx]

Greetings-

Ive been tuning my own cars for the last few years and have had all sorts of fun so far. The first software that I really became familiar with was ECMLink V3 on my DSMs, which is very well supported by a solid community that was very willing to guide me as I presented questions. Since then Ive learned ecuflash/evoscan, Hondata, AEMs nightmare FIC6, and some of the later Holley offerings.

I grabbed a Neon SRT4 a couple months back to try something new- Just purchased the MPVi-2 with pro features.

On the immediate agenda is:

- swap from the stock Map/tip sensors to 3 bar sensors
-swap the stock injectors to the Siemans 1025 (@58 psi)
- wire wideband into PRO Link for logging
-wire fuel 0-5v transducer into pro link for fuel pressure logging, or whatever i might be interested in collecting data on in the future

I haven't spent a ton of time learning the program yet, but see many nights of falling asleep at my desk reading ahead of me. At this point, I can see that there is some data that I am going to have to come up with for both the 1025cc injectors, and the 3bar Map sensor. I believe I have found this data, but would love a sanity check from any of you guys who are more experienced. If anyone speaks fluent ECMLink the info should be very relatable I hope.

Any input from anyone is majorly appreciated and I look forward to being a part of this community, and eventually having the ability to help others like me who want to do this.

Settings for 3 bar MAP sensor:

Map Sensor Linear: 61.85 kPa
Map Sensor Offset: 6.80 kPa
Map Sensor Offset: 0.10 V

Settings for 3 bar MAP sensor:

Map Sensor Linear: 61.85 kPa
Map Sensor Offset: 6.80 kPa
Map Sensor Offset: 0.10 V

These settings are correct assuming you're using a Caliber 3 bar MAP sensor, or the Mopar S2/S3 sensor for the NSRT-4 platform.

If you actually want to understand how these numbers are derived, the formula is:

y=mx+b

Where "m" is the slope (aka Linear value), b is the offset (in pressure), and x is the voltage output of the sensor.

Thank you so much for this!

Awesome- Thank you for making that crystal clear ! - Mopar S3 unit is what I have.

Now is there anything else that I need to change pertaining to the 3bar swap, or is that all?
