Nicely done, sir!

Shaker666

Chris, I think you can achieve your web GUI and real-time control using a TI MSP432 chip. I know because I've used it in the context of aerospace. That chip is probably one of the beefiest Cortex-M chips around, with 256K SRAM and 1MB of flash, plus a dedicated EEPROM of at least 32K or something. I...

I've got a very nice running 302 in my '00 Mountaineer tuned using CoreTuning's REAC4 definition. Recently, I discovered an offshore company called AlloyWorks which produces fully TIG welded aluminum radiators for my application as well as a fully fabricated shroud that incorporates a 16" S-blade fa...

What software are you looking for?

I'll second what Decipha posted, he also has a very detailed write up on how to dial in the idle for both EEC-IV and EEC-V. He put a lot of time into writing that and while it is not the easiest reading, once you wrap your head around it you're good. Thanks, Mike. http://efidynotuning.com/idleair.ht...

Yeah, those Xilinx chips have been a real PITA the last few years. In aerospace we're using them for flight computers (autopilots) and they had like a 52 week ARO. Total PITA, but my understanding is that lead time has gone away. Regardless, I'm with you guys on the IP part of Moates shutting down, ...

Shaker666

Likely the latter. There's a few folks that have access to the Ford internal documentation for the later strategies, but it's well guarded for obvious legal reasons. I can confirm that making an adjustment to these tables amounted to exactly diddly squat in my READ0 based calibration, though.

Shaker666

So maybe it's not my Failed MAF table? Based on the number of responses, it seems that perhaps others don't seem to think it is...

Shaker666

I'm datalogging a READ0 EEC-V and seeing some fairly highly load values when merely cruising and idling. I think I've narrowed it down to the Failed MAF Table that is used to infer load based off RPM vs. TPS, but wasn't sure exactly how to dial this in. I've got a WOT VE table for the engine based o...

Shaker666

What format is it in? Is it just a unit conversion issue you're dealing with?

Shaker666

I was able to read the tune off of a QH using a Jaybird successfully as well... just pointing that out because the resulting bin file would be what would be needed to flash the PCM directly using one of the direct flash tools. Right?

Shaker666

I've tamed a few radical cams so they idle and run like stock using the CDAN4 strategy, so rest assured, it can be done. The main things you want to look at are going to be some of the idle RPM correction rate time constants (TC_UNDER, mainly) as well as the Feedback Spark feature that is built into...

There's a lot of resources online, like Mike's website at EFIDynoTuning.com, but yes, an injector swap generally requires adjustment to the following functions and values: Injector breakpoint Injector high slope Injector low slope Injector's battery voltage offset curve Injector timing (optional and...

Shaker666

I'm looking very closely at the injectors now. I have not used a scaling percentage for the air or fuel, but I believe the max slope value that can be defined for this EEC is 53.64, which is about half of what it needs to be for Deka 80 lb/hr LU80 injectors at 65 psi. Tomorrow, I think I will swap t...

Having experienced a similar issue with CDAN4 on another vehicle, but having resolved it, I decided to build up a startup tune using CDAN4. I've attached the resulting startup datalog. You can see that the temperature readings are no longer erroneous as they are with my READ0 logs, but there is defi...

Shaker666

Tune is executing and with some careful footwork, you can actually get the motor running, but it's pig rich. I've already changed the oil once to avoid excessive crankcase oil contamination with fuel. Datalogging is possible, for sure, but several of the values being logged are not reading correctly...

@1fastgranada. I'm a newbie at all of this however, early on in my studying of all of EEC-V only, I learned that 96-97 EEC-V PCMs/bin files can be read but NOT written to (flash programmed). A veteran here could confirm that. Since I learned that, I have been working with 1998 to 2003 EEC-V PCMs. Y...

Recently built up all new powertrain for my '00 Mercury Mountaineer with Ford 5.0L V8. Updated motor should produce north of 400 hp naturally aspirated. Transmission updates to support the power level as well as driveshaft and transfer case updates. Cannot get any of the usual players to run this en...

What is the most comprehensive resource we have for the physical pinout of the J3 port and the related communications protocol used to communicate with the EEC processor? I've read the GUFB and CDAN4 strategy documents, but don't recall whether there is enough detail in there to develop a new commun...

Shaker666

I was not thinking of attempting to emulate the processor in the EEC. I was thinking of modernizing the FPGA/CPLD implementation the Tweecer and Quarterhorse used - ROM emulation via the J3 interface. I'm fairly certain that most run of the mill ARM Cortex microprocessors with enough peripherals and...

Shaker666

The jump in load is sure suspicious that something has happened. Can you tell what input caused the jump? For instance, did MAF voltage also jump at the same time? If not, then start looking for other causes such as misconfigured functions (extreme min and max values not represented in 1st column)....

Shaker666

Others are more knowledgeable with regards to the inner workings and logic flow of the EEC processor - feel free to correct me if I'm wrong. I believe the EEC tracks how many times the O2 sensors have switched between their "over" and "under" stoichiometric thresholds and once switching has not occu...

Shaker666

Not to threadjack, but I have a similar situation with my GUFB based Kenne Bell 2.2 Blowzilla setup on a 306. Same RPM range, the engine just falls flat on its face and has some voltage drop under boost and high RPM. Unclear what the issue is, but in my case I've considered the possibility of a "fla...

Shaker666

A vacuum or exhaust leak is going to make the sensor not read an accurate an signal and therefore provide an inaccurate signal to the computer. So you might want to focus on that first. You cannot run without the sensor - not unless you turn the sensor off in the tune, which is it sounds like you do...

Shaker666

I guess just throw some parts at it, but definitely fix any exhaust leaks. Replace all sensors and see what happens. I'm assuming you've got a check engine light currently. EECs are pretty hardy and not usually the culprit unless short circuited or something.

Shaker666

Ok, so AGANF strategy. Do you have a tuning device? A cursory look into what would work yields either Moates Quarterhorse or TwEECer RT, but the Quarterhorse would require a strategy definition from Core Tuning. The TwEECer definition for AGANF is built into CalEdit. If you have one of these tuning ...

96 f150 with 4.9 i6 and e4od. OBD2 compliant Anyway, so basically what im gathering is that seeing small voltages on all 3 "o2 sensor readings" despite only 1 of the 3 being plugged in is not cause for concern unless I pull the ADC on the 2 not plugged in to ground? Oh, very cool! I do like the 300...

Shaker666

What vehicle are you referring to? You might consider adding some details about your rig to your sig. ADC is short for Analog-Digital Conversion, which is how many computer systems "sense" and are able to read sensors. https://en.wikipedia.org/wiki/Analog-to-digital_converter For example, the coolan...

Shaker666

IMHO, CDAN4 is more widely supported. I have personally run that successfully before, but you might want to think about what driving an E4OD or whatever transmission you intend to use will look like with the strategy in question. I had chosen the CDAN4 specifically to control a 4R70W.

Shaker666

The microprocessor in the EEC is sampling the ADC voltage from those sensors, so if they're not present and the ADC circuit is left open, it's totally common to see the voltage float randomly and between extremes. A better way to run without those sensors would be to obtain the pinout from the senso...
