THIS IS GREAT!
I have been wanting to build one of these out of my arduino, im interested in this forum especialy, because I also have a Saturn, and from the look of your pictures it seem like they are close in years mine is an 2001 sl2 i curious what yours is is and if you have more pics of where you taped into the sensor wires.
Ive been looking at so many sites, and then I found this one in a Saturn so I decided this was the place to look around and of course view the relevant ads

What im really curious on is like i said some more photos, and if you sell a kit that can be wired into the arduino, or even a pcb with part,that just need to be soldered in, or a PCB, and parts list etc. im still new to arduino, but its an addiction you know, HEHE
PEACE and thanks for the info, and a great site

Hi, quick question on the injector wiring for my honda civic

instead of splicing into one of the actual injector wire (0volt), can I splice into one of the four injector wire on the ECU pinout?

any help is greatly appreciated. thanks in advance

Dont know about specific Honda but answer should be YES. It should be same wire, just closer to its source - signal comes from ECU to injector.
I had mpguino wired near to to ecu injector pin in Mitsubishi Eclipse.

Yes, this is how I hooked mine up. I cannot remember which one I used, but I had the schematic and used one of the wires at the ECU.

Not a Honda, but I did all my connections at the ECU on my 92' Metro.
As others have mentioned, it's the source of the signal to the injectors.

Hi everyone just finished my install on my Mitsubishi lancer
I was able to put the mpguino into the clock module and widen the slot and it is looking really good.
I have the injector wire direct from the injector and the vss signal from the back of the speedo.
I was able to use the connector on the back of the clock to do the connection so I can easily remove it if necessary.
My problem is that the mpg at idle looks high and the mpg seems to get lower the faster I go up to 70 mph and still continues to fall. Is there anything I can look for to fault find?
The distance seem to be fairly accurate. I have got the fuel aprroximately right but not done enough miles to get it accurate yet.
I bought a completed module from meelis.
Thanks

Hi, did you read documentation?
It is downloadable here: MPGuino trip computer - User manual/Installation

Quote:
InjType 0,1,2 – Injector type. If you press accellerator and in „Car sensors“ screen „Lh“ value is getting smaller, then change this value from 0 to 1 or from 1 to 0. If you press accellerator and this value is not changing almost at all, then maybe your car have „Peak and hold“ type injectors and you could try value 2.

That worked, somehow I did not download the manual you have listed
I am very happy with the end result. I was wanting to get another push button switch as I tried to modify the one you supplied to fit into the small space I have and it got a little twisted? Can you help me?

Good to hear you got it working. Would nice to see pics about your installation, where you put it?

Does that twisted button works? If it is not broken, dont bother to change it - if needed, twist it back to its original shape.
If you still need to replace it, go and search ebay with keyword "tactile switch right angle".
Here is one offer - 2 buttons 0.99$
2 Pcs Momentary Right Angle Tactile Tact Push Button Switch 6 x 6mm x 10mm | eBay
