  1. Are all bleed screws at the highest point on the caliper? If calipers get swapped left to right, the bleed screws will be at the bottom and you'll never get the air out.
  2. Is the charge warning light coming on in the voltmeter gauge? the alternator will not charge if that bulb is burnt-out.
  3. Glad you found the resources helpful. You may want to use a dedicated sealer depending on the color you choose. When you choose your color, many need a specific tint in the primer or sealer.
  4. I recommend filler after epoxy. Read the following: http://us.ppgrefinish.com/PPG-Refinish/Training/Training-Guides/Custom-Restoration-Guide Even if you don't use PPG products, it's a good resource on the steps from stripping to painting. Another good resource is: https://www.autobody101.com/forums/
  5. Without the year and model, hard to say for certain. Did you check the fusible links?
  6. Matt, Check out this video put out by Andy Whittle. The solution I came up with 5 years ago on my turbo ITB engine was a little more involved. https://photos.app.goo.gl/hpt3FkUcJnnSSQ9s2 I cut a FI manifold flange off and welded it to replace the flange on a canon triple carb manifold. I have 19lb/hr mustang injectors at the ports and much larger injectors in the ITBs. I got the idea from Joel's monster turbo stroker. Sam
  7. I would like 1 XL short-sleeve T-shirt in black Zipcode 70808 Thanks, Sam
  8. I have these in pretty good/usable condition. https://goo.gl/photos/nbf6ew3WX2LKHMcv8 Let me know if you need additional pictures.
  9. Where are you? What year Z? Which side?

    Agreed. This is why I asked for sources. I've searched pretty hard and have found no confirmation of a "fudge factor" or any other claims of inaccuracy in the PW calculation, intentional or otherwise, in the calculations. In my experience, Megasquirt algorithms perform "as advertised." That is, they produce results in accordance with their documentation. There are no hidden "fudge factors" to protect users from their naivety or inexperience. An overly rich condition can damage an engine just as an overly lean. I think I see the disconnect. The PW generator example you give is calculating PWs for running engine conditions. Megasquirt uses the ideal gas law to do that. (The spreadsheet you show may use the ideal gas law as well, but the formulas are hidden and password protected, so I can't easily tell.) The TunerStudio Req_Fuel generator calculates the PW (time) required to deliver a quantity of fuel to produce a stoichiometric mixture in one cylinder' volume of air at a standard atmospheric condition (1000kPa @ ~70degF IIRC). This number is then adjusted by the megasquirt algorithm based on the amount of air the tune tells it is going into the engine (expressed as VE, or the percentage of a perfectly filled cylinder under standard conditions - looked up from the VE table) and the ideal gas law which adjusts for temperature and pressure. Again, no fudge factors, just science. I might agree with you somewhat on a MS1, but this thread is about MS3, which while relatively inexpensive, is quite capable.

    I've never heard this before. Which advanced forums? Can you provide a link? I've searched and read the MSextra site religiously for the past 8 years and have never seen any mention of these issues. The Req_Fuel algorithm that TS uses is here: http://www.megamanual.com/v22manual/mfuel.htm I don't see any "fudge factor". What do the other PW calculators use? One thing I do know is that if you want to get a good VE table, it is critical that you have a good understanding of your injectors. You must have the correct deadtimes and voltage correction as well as the correct flow rate. (If you have exceptionally large injectors, you will need to calculate the small pw correction curve as well.) This requires testing your actual injectors with your injector drivers. That's why TS and MS provide the test modes. https://www.youtube.com/watch?v=lJgi8l-2XG4

    Reqfuel is the pulse width required to provide a stoich mixture at 100% VE. It is determined by the flow rate of the injectors and the displacement of the engine. Getting it correct is essential if you ever want to change injectors and don't want to have to retune everything. VE is the proportion of air, relative to the total displacement, that is entering the engine under the defined MAP and RPM. With incorporate AFR on and a correct VE table, the fueling algorithm will essentially calculate the pw for a stoich mixture and then adjust the pw for the desired AFR. This allows you to adjust the desired AFRs without changing the parameters defining the engine characteristics.
  13. I've had a license plate lightbulb burn out in such a way that it created a dead short. Talk about a bitch to diagnose.
  14. Never heard of gravel guard. I've had good luck with 3M products.
  15. I wouldn't use bedliner on my car. The pros use epoxy primer. That's what I use followed by 3m rockershutz.
