to sell me? how much?

thanks another time!

Can't you get those basic chips from some local shop ? And what comes to motorola. It has to be prommed with megasquirt code before to use it. It won't work without it. I'm guessing that people at this forum isn't gonna sell anything to abroad without any proof. Why don't you try http://www.diyautotune.com ? It even has Italian language at their site.
Service parts section at the diyautotune.com. You can order a Map and working cpu from there.

We have also parts and could sell worldwide.
That egt ic we have only on GPIO-EGT kit.

Because at the local shop i can order only mpx4250 and ad595aq, togheter 50 € and i want try to spend less. the motorola i can't order at local shop and i don't find it on ebay. i know that you must insert a firmware in the motorola before the installation of it in the megasquirt, and i also know that i had to have a particular programmer for the chip. i've already do the programmer, this: http://www.not2fast.com/megasquirt/mega ... gaprog.pdf

on diyautotune you can find also the Bosch BIP for the ignition..


i'm trying to spend less as possible

I've finisched the Turtana, with MPX4250GP, AD595AQ and i bought the Motorola MC908GP32CPE but i don't know how put the firmware MS Extra in the Motorola chip. I made the Willette Megaprogrammer but the software by P&E Microcomputer System "prog08sz" say me "Apro exception" error. I use win7.

there is another way to put the firmware into a vergin Motorola?

[JaniM]

I think your computer is too fast. CPUeater might work.
Easiest way is find old WIN95 and slow cpu with com-port, then it will work with Willette.
Or buy preprogrammed chip.

i downloaded "virtual box" by Oracle and when i'll go home i'll install win98 to try this.

another question: at right of Motorola's socket there are 3 holes, near oscillator, in corresponding of pin 10 and pin 11. what are these?

[ricki158]

hi all! i made some modifies at the pcb:

- add jumper for the bootloader mode
- change the L7805 with the LM2937ET-5.0
- change clock capacitor

now i'm looking for another modify for save the CPU from the overtension from 5 volt of the sensors with a zener 5.6 volt between pin 31 and pin 32 of the Motorola

Mikä tuon fet 9 tarkoitus on? Mitä toimintoa ohjaa? Tulee prosun pinniltä 15 fettiin ja siitä suoraan ulos liittimelle jossa ei ole Turtanan kuvassa selvitystä mikä on.
