Default Basic Stamp / PIC microcontrollers

I was thinking of a way to build myself a little computer to control everything in my car and remembered playing with a Basic Stamp 2 in high school. I realized that if I could tap it into all the engine sensors then with a couple servos (ith needles through gauge faces), an LCD screen and a few buttons i could have something like a STACK gauge cluster. Then I thought why not link it through the TTL port on the stock computer. I'm not sure if that's possable, but I havent been able to figure it out yet. Now I'm kinda thinking that it might be possable to use one to tune the ECM with a emulator, they already have COM port connections built in.

Anyway, if anyone knows anything about these, that would be helpful, i don't know ----, about them.

This video was linked to the datalogging port of a Honda OBD1 ECU

wow.. looks very nice.. but how is that done? u need to edit the vid too , right? you i means you record two vids, one of the datalogging info and other about and after that you edit vid for looks like that..

The RS232 port will output data like it would to freelog, you need to work out a way to decode this information.

There are a few people around who've used PIC's to control LCD based cluster's. There was a thread about it on pgmfi.org with some impressive projects. You can take the outputs you want from the plugs on the back of the cluster and then interface your EGT probe and WB02 to give you a variety of outputs.

You'd be better in alot of ways using something slightly more feature packed then an obsolete pic. Something based on the 8051 architecture with a C compiler would be my preference, the ATMEL AVR series have nice easy to use registers and come in every flavour imaginable.

I think I'll start with Stamp based for now, I have zero experience in building this stuff. Once I get a little practice then I'd be glad to move on to something more powerfull.

I'll check PGMFI, I tried to check there the other day, but it wasnt working. I think it could be my ISP.

I was looking into using an OOPic to monitor boost level via a second MAP sensor and then operation a solinoid based on that info. IE: Homemade electronic boost controller. And then I can set it up to do basically anything...

Eliminate boost creep and spike altogether. Set up a switch on the dash so you can go from your 93 octane boost level to you 110 octane boost level in seconds.

DOC from PGMFI (very clever fellow) created this and posted it. He has done quite a few 'trick' electronically intelligent mods in Hondas.

http://www.doctronic.at I believe is his site.
