This is a new install. I've tried two computers. One with W11. One with W10. No known errors any where. The Log file just says "Started" and gives the time. Both computers will boot BE without the Dongle and boot unregistered. Both computers with the Dongle installed will boot to the Splash screen a...

My BIGGEST screw-up to date: Ignoring ITHBMA. My second biggest screw-up: Assuming the fuel filters were clean. If you haven't done so already, dial in ITHBMA. http://efidynotuning.com/ Has an excellent write up on how to do this, (Under "Idle Air") HOWEVER this is NOT a "One and done" as you'll be ...

I created quite a stir on this topic a while back: https://eectuning.org/forums/viewtopic.php?f=2&t=23195 Some say a MAF curve is "gospel" equal to the ten commandments. (Thou shall not change! EVER!) I say it is a dynamic ever changing entity. The best you can hope is to get the MAF close for a giv...

Two things to check come to mind: The external Fuel Filter. On my 1995 it was higher than the fuel tank in the rear axle recess area. The Internal inlet sock inside the tank on the fuel pump inlet. Mine was varnished so bad that part of it would hold gasoline. Now, pray that the external fuel filter...

After a couple test datalogs over a predetermined route, I can find no real difference in fuel mileage by running open loop utilizing lean AFRs over closed loop. I left the timing unchanged both in open and closed loop. My cruise ignition timing is still advanced like a vacuum advance would do in th...

To those reading this and wondering if the discount non-Ford injector set is worth saving a few bucks: If you go to :https://performanceparts.ford.com/part/M-9593-LU47 , at the bottom of the page are calibration sheets for ALL of Ford's injectors. Both old and new injectors are listed. Yeah, Ford's ...

Yer in luck. I used those same injectors on my 408.

OK, here are my experiences that made me advocate for adjusting the MAF Curve. I bought my Quarterhorse and Binary Editor and decided it learn to tune on my PURE stock engine. The stock car was a dog! Clearly it was running extremely lean as any throttle opening past 1/4 throttle elicited loud pingi...

I 100% agree with both of you that the DESIGN of the PCV system is you pull metered air in after the MAF has measured it thru the engine and back out thru the PCV valve. My only argument is that as the engine wears, blow by increases. Over time the negative flow into the engine decreases and at some...

I’ll post my “One size fits all” MAF response shortly. As to my contention on the PCV valve, from Wikipedia: https://en.m.wikipedia.org/wiki/Crankcase_ventilation_system From Summit Racing: https://help.summitracing.com/app/answers/detail/a_id/5233/~/what-does-the-pcv-valve-do%3F From an Auto repair...

I once too believed the MAF curve was the 11th Commandment- "Thow shall not change!". That is until I proved to myself otherwise. One size fits all as long as it is big enough, right? ( I had to create mine because I bought a slot MAF and uncalibrated housing.) I'll post some before and after MAF Tr...

ChsReb

All Good points guys. A interesting an insightful discussion. To follow up on a point by point basis: 1,) Is turbulence at the MAF sensor an issue. YES, Definitely!! Going back to my HVAC days, we always chose a point to drill the hole for a Pitot tube or Hot wire, 8-10 duct diameters down from the ...

ChsReb

My original contention remains: Anything done to alter the way the engine breaths alters the MAF curve because you alter the volumetric efficiency of the engine. A MAF curve is only accurate for a specific complete drive train. Actually I’m being really generous with that statement. My stock MAF and...

ChsReb

Your MAF curve is a relationship between fuel and air based on a known air flow based on a SPECIFIC volumetric efficiency. It is all about cylinder filling and exactly how and with what you fill the cylinders. Another way to look at it, let’s suppose I had a terrible exhaust system. The result of co...

ChsReb

In a sentence: Lower Differential pressure drop across the filter. The engine breaths easier at the same throttle opening. Same thing with headers on the back end. If I make it easier to breath, I get better cylinder filling. Better cylinder filling produces more HP at the same throttle opening. Now...

Linux will always be a year or more behind Windows with new Hardware.

I should have mentioned that the video you indicated is now private and unviewable. Linux is my, as you put it, “Daily Driver.” I use it for all the daily chores. Windows 10 is the speciality car.

Linux is just another tool in the computer tool box. Some things it does well. Some things poorly or not at all. I’m definitely not a coder.

Lots of 20 & 30 somethings around here are still modifying cars. Most just don’t want to spend the months long learning curves for retuning or should I say reprogramming a Computer controlled car. That means carburetors are still king of the roost for now anyway. Gearheads still hate the Prius, and ...

Have you dialed in ITHBMA? If not go to efidynotuning.com and read the “Idle Air” section. This is a royal pain. As you raise the ITHBMA scaler you have to raise your idle air setting. I went .1 lb/min and + 5% each time in idle air. Failure to increase idle air makes for a car that probably won’t s...

Guys, Tell me what I’m missing here. I thought the goal was LOWER carbon emissions. Now to BEST get that you run lean with advanced timing during cruise.
