Re: Back end engineering software from the factory

According to various sources of information... Ford in the 1980's used DEC-20, DEC-VAX, PDP-11, and LSI-11 computer systems for strategy development. They used remote terminals to log into a development environment called VECTOR that ran on DEC-20 and VAX mainframes. VECTOR was developed in-house at...

Re: Calibration vs Tuning J4J1 Why can't I just input known Injector/MAF values and be done?

That is the way that I understand decipha's methodology. He also says that at least at 1.0 the NB's are faster responding and more accurate than the WB and dialing in fuel by KAMRF will be easier, faster, and more accurate than eyeballing an AFR meter. I think you'll still use the WBO2 to confirm th...

What I'm not totally understanding is how you are using the hegos to tune The open loop WOT fuel... looks like the strategy is to force closed loop at wide open throttle, and then I lose it. I'm reading and retreading your write up and can't figure out what you are doing. Last, I'm curious why you ...

Re: Execute Enable Register?

So is it accessed via the DAR like other RAM contents?

It sounds like you're saying that normally if you use the RAM's SPC to read, it probably just floats the bus and you get 0xFF's unless the EER was written 0xAA.

Please confirm my ignorance or deny my understanding :lol:

Re: Quarterhorse II update desired

The way I would have done it is to have an SRAM backed by the KAM power rail for working memory and flash for long-term storage. Whenever power is lost and restored, the contents of flash would be loaded to SRAM so you'd never be stuck with a dead car. You could use DRAM in self-refresh mode when th...

Re: Suggested FAQ - Different methods of hooking up WBO2 sen

AFR meters usually have a 0V-5V linear wide-band output and a 0V-1V simulated narrow-band output. There just aren't that many 5V analog inputs into the EEC and they are all critical except for the EGR position sensor. So if you want to feed the AFR into the EEC for datalogging, I think your only opt...

Re: Moates J3 help!!!

The fuel pump constantly running is a symptom of a bad EEC/corrupted tune/malfunctioning J3 device/bad connection to the J3 port/etc.

Pull the F3 and clean up the J3 contacts, but don't reinstall the F3. If the pump still runs constantly, then I believe your EEC is toast.
