Esteem 1.8l ECU PINOUT

[Oxide_Zer0]

I will be install an SAFC soon, I need a 1.8l Esteem ECU Pinout. Also does the 1.8l run on a map sensor or MAF Sensor?

The diagram that I found says "MAP SENSOR" on it, the wires that go into the ECM for the map sensor are labeled "P" and "G" but there are no pin numbers on the rectangle that represents the ECM, the third MAP SENSOR wire is marked G/R and goes off to the back side of some other sensors and appears to be some kind of ground but I could be wrong about that.

hmm that makes me wonder if I can get the ecu socketed and chipped then tuned. either way more then anything I need the ecu pinout

but thanks!

Ok, I did more digging and found the diagram that has the pin numbers on the ECU, this will be way easier if you have the manual in front of you and I'm just assuming that you don't have it.

Go here and download the manual (it comes in 12 parts and is HUGE): Suzuki engine manual for sy413, sy416, sy418

Download the first 12 RAR files (the 13th is not there for whatever reason but everyone says that you don't need it), then create a folder called "Suzuki Manual" (or whatever name you want to give it) within that folder create 12 more folders called "index01, index02, etc.) then each RAR file has to be unpacked into its own folder (part01 in "index01", part2 in "Index02", etc.).

Once you have them all unpacked open up folder "Index01" and click on the "TOP.pdf" file (this file opens the entire manual), hopefully you are opening this on a Windows PC it acts kind of weird on Linux systems.

Once it opens click anywhere on the page, on the next page that appears there is a big NEXT button/arrow symbol in the upper right corner, click it twice until you are on Page 3/3.

Look for "Manual Group (14)" at the bottom of the list, the only thing click-able on that line is the Language Group "E,F,G,S,D", once you click on it this part of the manual is multi-lingual due to electronic symbols being universal for the most part, but some of the sensor descriptions make more sense in Spanish and French then they do in English which was rather helpful.

On the next page that popped up in the left hand frame click on "Section 8A-7".

Then scroll down to Suzuki Manual page (not the PDF page) "8A-7-47" and look in the lower right corner of the schematic and you will find the MAP Sensor with numbered pinouts on the ECU.

Hopefully that all made sense.
