i have made many test to find some logic with the Hex code and i didnt find it.

its possible to run the odometer up then 8mhz, 28mhz its the limit, it take 2-3 day to go 999 999km.

its very fast lol

i hope to know how modify it.

im working now on french version of this How to,(and my own signal converter)

i will post it on many french canadian forum.

orthello needs to explain the ODOMETER RE-WRITE better because i am interested in it too now.
I found a tool..... years ago.... that does the calculation.

ButI can't do attachments in this forum.

The last 4 lines contain the ODO meter reading.

i find a programm to do the calcul.

Tachosoft

not very hard to find on the internet.

i will probably host it soon

Can someone help me with this. I am still in the process of stealing the signal from right behind the Integra cluster to monitor the Speedometer and ECT temp. The data that I got from Konerri, was it gathered from the Integra cluster? If so from where, was it the wires right behind the cluster. Also isn't the speedometer a linear type signal, meaning if it was 60 hertz at 50 MPH shouldn't it be 120 hertz at 100 MPH? I'm pretty quick at learning so if someone could help me that'll be great.

i simulated the signal going to the integra cluster using a function generator. Now the figures are not going to be perfect since the integra cluster is not a digital readout. i basically took the best guest as to where the needle is pointing to. And Yes, the signals should be linear.

I only ask if its linear because your information on the speedometer doesn't look to scale (not at all questioning your work). Also I was wondering how did you get the temperature readouts to the integra ECT? Can you give me the high temp at 0V and low temp at 5V? Anything will help thanks.

Have fun with TachoCalc

NOTE!!
First: Type the desired ODO reading
Just Then: Choose car -> Honda -> S2000

It wil give you 4 bytes.

This 4 bytes need to be put in the eeprom from 00C0h to 00FFh

For those who can calculate HEX will see this is an address range of 64bytes.
This is right!
The calculated bytes are repeated 16 times




Oh and.... set 005Dh and 005Fh to 00 to enable the mph/kmh toggle button ;)

any possibility i can have a module/converter made? of course i would pay for parts and labor :thumbup:

i can also be the guinea pig for testing :p

aaarrrggghhh im lost trying to pick the bones of this now to get a wiring diagram and parts list so i can have my cluster working as my water temp needle has broke has anyone got a how to yet

Assuming you're using a PDIP40 version of the ATMega16 (huge processor for this task btw.)
Use pin 16 (INT0/PD2) as the VSS input
Use pin 3 (AIN0/INT2) as the ECT input
Use pin 18 (OC1B/PD4) and/or 19 (OC1A/PD5) for PWM output

Note.... I do NOT have experience with AVR chips. This is just based on what I found by using Google ;)

Hint: Servos are also PWM controlled. There are tons of documents about how to control a servo using uPic and AVR chips including sample programs/sources in PicBasic and/or C.
