Jaguar 0.6-alpha Assembly Guide

[Fred]

SUCCESS! ! !

Good! :-)

You guys walk on water!

Only at night ;-)

Mike, good work on diagnosing the win driver issue. Such things do not cross my mind, Linux "just works" for me, every time.

I'm looking forward to downloading some firmware (hint Fred), connecting to my "superstim"

Tell me your expectations. You won't get the scheduling change you need without wiring it up to your vehicle or doing it yourself, but a decoder for 50/50 is easy enough.

and badgering Mike about how to configure things.

You're in for a bad surprise, and one of the reasons I don't recommend FreeEMS to "users". Only tables are tunable, all config must be done in source for the time being.

Fred,
I thought that I had made my "expectations" clear from the beginning.

Initially I would like to have Jaguar and Free EMS a direct replacement for the MS V2.2 board running a modified MS1 Extra code on my daily driver '95 Ford E-150 I6. TFI ignition, alternate bank fired. Once I have that running to my satisfaction then I can try almost anything that you feel would show that Free EMS is a superior system. Having said that, my preference would be to retain the stock ignition and injector wiring to permit easy return to Ford EEC-IV if things go horribly wrong, as I can do now.

I can modify Jaguar as needed. But if I have to modify firmware or software then then that is beyond my capabilities at the present time, perhaps even for the foreseeable future.

I can contribute ideas, points of view and real world testing at this time, but that's about it. It seems there is a big difference between "users" and "testers"

Perhaps I have been unrealistic in my "expectations".

Andy, are you still selling the connector PCB? Fred, your comment about the "tunable tables only" is a little scary. Can we tune this in tuner studio or tunix on the fly (or maybe 1.test 2.burn, 3.goto line 1) ? Oh I hope so. Not many of us are "code warriors" like you and Andy and maybe even a large percentage of the users. Man I would love to wire this up, get a rough start and start tuning through the laptop to smooth the idle and get the A/F table down to somewhere where it wont melt the pistons or choke the drive through cashier. Im still in, but am afraid Ill not be able to lend any code help. I wrench.....

[Fred]

Take it easy! We can get you that, but without the same output styles. But you can't have the scheduling feature just yet, I simply do not have time. That's all. For now, you can have a 50/50 decoder and you can get it working with that, and injection will be OK, but TFI will be wrong. I can't solve that for you without a little work that is high risk, and thus, it will take time to verify that work, so as not to place existing users at risk.

pishta, we'll talk soon, I'm pretty close to you now, but not quite there yet. Will explain, but you don't need to worry. It's not THAT hard. However, there are NO users, yet, and won't be, for some time. You won't need any code, I don't think, unlike E40Dnut, who does need a few important lines.

Fred.

Sure, Im cool with that. Im nowhere close to a running setup but when I get there, ill be very vocal about it. Turns out Im on Vacation for the next 2 weeks after Sat.! A little southbound road trip isnt out of reach.

JHC, those MOSFETS (even Andy's new part number) are a bitch to find in stock! If they are obsolete, why are there not new part numbers?

[DeuceEFI]

Andy, are you still selling the connector PCB?

I have only etched one of the connector PCBs at home. The reason is it really doesn't fit well in the enclosure with the connector.
Others (including myself) have soldered wires directly to the connector pins instead of using the connnector PCB.

As for the MOSFET part numbers, ST Microelectronics has been replacing their non-RoHS compliant part numbers with RoHS compliant part numbers this year. I have been updating the Bill Of Materials in the Jaguar repository as part numbers have changed, the most current BOM can be found in the "dev" branch.

[E4ODnut]

Fred,
OK.
I'll wire the pin outs as per Andy's post on the subject and wait for some suitable firm ware to load. When I have that I'll connect to the superstim and play with it and get to know EMS Studio. If you give me a link to the source code that the .s19 is derived from I'll study that and see if it helps my "C" education.

[Fred]

For the source code do this:

Code: Select all

git clone https://github.com/fredcooke/freeems-vanilla.git
cd freeems-vanilla
git checkout dev

For playing with it on the stim, try this: http://builds.freeems.org/firmware/dev/ ... f69.s19.gz

That may get you some outputs on some pins, and may sync, or may not. At the least you can play with EMStudio, which is a good idea to do.

Fred.

Andy,
On your schematic 12vdc-switched-outputs connects to 12v-sw2 and P32. What do you want P32 connected to?

Fred
Just to confirm you want me to use RPM0 for trigger input. Delete R22, R23 and R83.
