Re: Could I....

It is outside the scope of the initial firmware but that doesn't mean it couldn't be implemented at a later time. The main issue is what has been mentioned on the MS forums each time this has been brought up: safety. Unless there are external failsafe mechanisms that won't let the cruise control run...

Re: Progress report

The board should be ready but the firmware to fully use the SD card may not be fully done by then. Every effort will be made to have at least some minimal functionality for it at that time.

Re: Progress report

I have put a bit more information on the board in this post: http://forum.jbperf.com/viewtopic.php?f=9&t=8. There were some posts on the msextra forum but they were lost in the forum crash. I'll have a small batch of boards made in the coming weeks which means I should have some available around mid...

I/O Extender Board Intro

Since the post on the subject was one of the casualties of the msextra forum crash, I thought it was appropriate to introduce the board here instead. First, the board is based on an 8-bit Freescale microcontroller that has 24 12-bit ADC channels, 10 timer channels, CAN, 2 SCIs, 2 SPIs, 2 IICs and mo...

Re: 8 driver P&H board

At this time, I don't know when or if this will happen. I have the boards and components but I don't have the case or connector. At the moment, the demand isn't high enough to make this a logical choice because I'd have to sell the case at a higher price than you can get it elsewhere. The component ...

Re: Progress report

It's using the Freescale 9S08DZ128. It's an 8-bit CPU but that's more than enough for this type of application and it does have a lot of useful features. It's too bad that the msextra forum has lost a lot of posts because I had more information there. I'll have to re-write it and put a sticky here. ...

Re: why not sequential injection section??

Porting the code to CodeWarrior would be a huge job. And since the gcc compiler is free and CodeWarrior is not, there is no advantage with going to CodeWarrior and there should not any issue for anyone to use gcc. Of course if you're used to CodeWarrior you'll need to adapt but if you just want to c...

Re: why not sequential injection section??

While I'm the one who wrote the sequential injection code, this is an MS2/Extra related subject and would be best discussed on the msextra forum since it is part of an official release. However, if you have specific questions or comments, I don't have a problem about discussing it here especially if...

Re: regulator getting hot!

The JimStim will work fine without D4. It is there to help protect the CPU in case of a short but it's not a total protection. I would still recommend that you use it. The first thing to protect the CPU is to avoid static electricity (like for any electronic components). The second thing is to make ...

Re: 8 driver P&H board

Yeah, your conversion is correct. I think that the specs show a big range in resistance and wattage because it also mentions from 1 to 4 valve seats. So basically, this for 1 to 4 injectors so it looks like you will be fine as long as you use one p&h driver per injector. They seem to have the specs ...

Re: 8 driver P&H board

Dan, The board is designed to use the Ampseal connector. However, you can solder wires instead and use an external connector with the wires going through the case end plate through rubber grommets. Doing it this way, you can use any automotive connector type you prefer. The connector pin out is show...

Re: regulator getting hot!

The U4/U7 mistakes will not have any impact on the JimStim's CPU because it's not directly in contact with the MS board. If you're talking about D1 and D2, it's normal that you have nothing on one side of D2. If you're talking about another diode then the problem is not that you have 13V on one side...

I should add that I don't have the connector in stock either. It is an Ampseal 23 position.

You're correct that the V2.1 board is available. I also have the components available but I don't have the case. The bare board is $30 plus shipping but I'll have to get back to you about the component kit price. The case is the EAS-200. This is the partially completed board (transistors for the dri...

Re: regulator getting hot!

Rick, Are you talking about the JimStim regulator or the MS regulator? If you're talking about the JimStim then you need to check D4 and see if it is shorted to ground. If you're talking about the MS voltage regulator, then you need to check D19 to see if it is shorted to ground. However, if removin...
