  1. forged rods

    Make sure you get the big and small ends checked for size and re-sized if needed. I've gotten 3 sets of China rods that were all undersized from spec, and a few that were out of round by a few thou

    I hate how the engine always rotates when using the harbor freight support straight across the engine. That's a good idea for the center support. Where'd you get it?
  3. Make sure all your ignition system components are fresh. Get a new cap and rotor if they look scored/worn inside. Get some nice fat spark plug wires, the 8mm Kingsborne ones are quality: https://www.kingsbornewires.com/Volvo-850-C70-S70-and-V70-Spark-Plug-Wires-p/9135700.htm Get NGK BKR7E plugs and gap them to .026". If you still have blowout then I would replace your ignition coil. The MSD blaster coil is the most common aftermarket choice, it's not really that much stronger than stock, it's just cheaper. The problem with the blaster coil is that it needs a lower amount of dwell than the stock coil, so unless the dwell times are reduced in your tune the ignition coil will fail quickly. The octane of your fuel has no effect on spark blowout. A can of octane booster will have no meaningful effect on the overall octane of your fuel unless you only have a very small amount of fuel in your tank or use a lot of booster.

    That's just for the amount of fuel injected when cranking.

    @ejenner2004 is ME7. None of this thread pertains to your car.
  6. Roll Center Adjusters For P80?

    Roll center and the camber curve are related to relative location of pivot points of the control arm. It doesn't matter what you do to the position of the arm, if the pivot points don't change location the roll center and camber curve will remain the same. It might be worthwhile to machine a custom piece for the AL control arms that accepts a taller ball joint. I think this would be easier than retrofitting a P2 subframe.
  7. Roll Center Adjusters For P80?

    I just searched ball joint extender and that popped up as the first image. It would be quite easy to turn on a lathe if you brought someone the correct measurements. The tie rods would be easier, all you need to do is flip the side to which it bolts to. It currently sits on the top, you just need to make it bolt to the bottom. Easiest way to do it would probably be to drill out the taper and press in a smaller sleeve to accept a universal tie rod end.
  8. Roll Center Adjusters For P80?

    It's not an easy design to modify. The goal is to get the control arm to sit level with the ground, by dropping the pivot point of the ball joint. You can change the angle of the arm with the aluminum control arm by placing a piece of bar in between the control arm and replaceable ball joint, but this won't actually do anything as it doesn't drop the pivot point. Is this what you were thinking about @andyb5? It being a pinch bolt connection on the knuckle makes things harder. The only simple way to do it would be to make a pinch bolt extender like this one: This isn't really ideal though since you're adding a lever arm and increasing the amount of force the knuckle has to take. My hunch is that it would be fine, but I wouldn't be confident enough in that hunch to make a product of it. The only real solution would be to create custom control arms. Or, swap in a P2 subframe and steering rack where you can easily drop the ball joint, since it is press fit into the hub.

    TunerPro doesn't manage memory well. Make sure the tablet isn't using more than 75% of its' memory. Also, make sure you don't have the data monitors view open (even in the background) while logging.

    Why not use the ACT disc? That's what I used and it is a much beefier disc than the SD693.

    This LDR routine talk is exactly why I created the 'boost quickener' mod. Any time you floor it and the current load is 1.25ms (can be defined) below the target specified in the target load map the TCV is held shut and the P and I factors of the LDR routine are set to 0. When the load is within 1.24ms of the target load the LDR routine resumes. This guarantees maximum spoolup and minimal overshoot. Regarding the MIL flash due to knock, I need to update the patch file as I made some mistakes in the code. I've reworked it and will upload a new file soon.

    That was just a quick idle and throttle blip from my car. Clutch still isn't working so I can't get running drive logs from it. I shouldn't have posted that, because it really makes the control look much more ineffectual than it is. The new routine directly replaces the stock I factor RPM vs load lookup. I quickly ditched the single axis, non RPM dependent lookup and replaced it with a AFR deviation vs RPM lookup map. The AFR deviation axis is in units of AFR and the scale of the axis is determined by your AFR gauge. I still need to play around with the AFR deviation axis and tuning of the factor, but the above map seems to give pretty good control of the AFR, even if the tuning of the 'VE' map isn't so spot on. At idle I find that with an I factor of 1, and the P,D variables set appropriately, the AFR will stay within .1 of the target. I think the next step in wideband control would be feeding the AFR into the ECU via serial input instead of analog 0-5 voltage. I'll send the code to Piet and Venderbroeck if they want to incorporate it into their wideband regulation mod. I'd appreciate any feedback for tuning of the map.
  13. Tuners Rejoice! Free Tuning For M4.4!

    I'm going to redo the map lookup with a better map lookup. I'll use an interpolation factor and the axis will be the AFR deviation in .15 increments. I'll include a ROM variable that is equal to the slope of the wideband curve so it will be easy to port to different tunes. I'm starting to wonder about the effects of exhaust gas velocity though; maybe I should create a 8x8 RPM vs AFR deviation map?
  14. Tuners Rejoice! Free Tuning For M4.4!

    It worked. I just need to figure out how best to tune the map. The AFR swings look over exaggerated in that shot, but I have the axis set to a pretty narrow range, from 10-16. Right now the lowest I value is 8, but I bet I could set that even lower, perhaps even to 0.

    Have you looked in the DAMOS? A quick search and I found TVSA0G,{Verzögerungszeit für Schubabschalten 0. Gang (LL)}. 6x1 map located @ 0xCAD9 in 608. Conversion = 11.9040 * X, 1=12ms. X axis is 0,1,2,3,4,5. There appear to be other fuel/time related tables in the SA_WE map group as well.
