    Boost control

    Haa Haa . Just had a big argument on Guild Of EFI Tuners on why a simple MBC can sometimes be the easiest solution to Boost control on a DD. Big arguments that B&S MBC is archaic, didn't have Boost taper, Boost per gear, Traction management etc. Millennials couldn't grasp the fact that not everything has to be electronic. OP was fighting a Boost curve that wouldn't stay linear with his MS2 Boost management ( MS3 Boost management is much more sophisticated than MS2 ) I suggested a simple B&S MBC as that would be more than sufficient for HIS needs. Man you should have heard the whining and bitching from the Internet coaches.

    Check with WilWood. There is a recall on some of their MC 's. https://www.wilwood.com/Pdf/Recalls/RDCONL-17E030-0986.pdf Recall was on 7/8" tandem cylinders, but I've heard reports of some of the 1" cylinders failing as well. Happened to my buddies Camaro with a WilWood 1" Polished MC.

    L6 DIS Brackets (LSX) Are Available Once Again

    Are these available to fit the D585 Yukon Truck coils?

    Turbo race car, high or low compression ratio?

    Modern combustion shapes that are not detonation prone and cooling of head really affect this. I do know that some of the 510 crowd are running really big compression with AV gas or racing Fuel ( VP C16 ) . E85 would work as well. Example 1: Turbo 2.1 Liter 510 with 10.3 CR on 16 lbs boost making 300 RWHP. Track day, Autocross and Hillclimb car. Can be driven on street. Water/Meth injection . Owner brews his own street fuel in garage for cruises!!! Not the safest or most practical option. No E85 here. VP C16 for track. Carburated!! But very well sorted. Example 2: Local 240 Z on low compression . L28 all the tricks including big intercooler and C16 Race fuel, but can run on pump gas with reduced Boost and Water/Meth. Makes 450 RWHP. Can't remember exact boost, but I think it was around 15 lbs. MS2 ECU.

    L28et powerband issue

    It would be fairly rare for a L-series to skip a Tooth. On the chain. Particularly on a fairly new engine with only 18K on the chain. I think there are other issues going on here.

    You're welcome Derek. We cam work on the rest of the Tune a bit later.

    I don't give a F**k what MSD advertises. The engineering papers on this coil and field experience from knowledgeable racers who have run this coil on Inductive say otherwise. And I ran it on my 1976 280 Z . Have you ever run one one. have you ever run a MS ECU or tuned one? Stick to things you know about ZH. You are clueless on this subject. BTW... for newbies to this Forum. ZH likes to Troll my posts. Don't feed the Troll.

    1: Remove the condenser. Not needed with Ms and could be causing an issue. 2: Plug gap .041" is way to large on a Turbo engine. I suspect you bought NGK plugs with a -11 as a suffix. Such as BPR7ES-11 Those are wide gaps. Get the Iridium or regular Copper core NGK plugs with no suffix. Such as BPR6ES or BPR7ES ( 7 is a colder heat range ) . The NGK plugs with no suffix come pregapped to .031". Gap them down to .028" if your Boost is higher than about 8 psi. The Wide gap plugs cannot be gapped down to .028" without putting a weird angle on the side electrode that will wear excessively fast. 3: I'll look at your .msq later this morning. Have a Remote Tuning session scheduled.

    Grounding is also very important . Particularly with a Nissan Optical distributor. The MS ECU main ground should be grounded on the Intake manifold. As per MS Extra instructions. The factory ground point on the Intake manifold is ideal. Do NOT ground the ECU to the Chassis or worse to the Battery negative terminal. The starter can pull over 150 amps when cranking and this can induce enough voltage in the ECU ground wire to feedback and disrupt or even damage the Microprocessor. The ground wire on the 4 prong plug should go back to the ECU sensor grounds. Then add an additional ground wire from the distributor body directly to the Intake manifold. And make sure that there is a good ground connected from the engine to the Chassis grounding stud on the Firewall.

    A very good Coil that matches with the BIP373 drivers is the AllStar 81230 E-Core coil. AllStar is a large supplier to Circle Track racers. Very reasonable price and this coil will pack a wallop!! Set nominal dwell to 4.0ms . Available at Summit, Jegs, Amazon. Justs about anyplace. Make sure your Primary wiring to the coil positive and negative are large enough. 14 gauge minimum

    PS: What new condenser are you referring to? There is no condenser used on the 280Z distributor. At least not like on a points system.

    What precisely is your Coil make and model? What plug wires are you running? What plugs and plug Gap are you running. Next post up your CurrentTune.msq and I'll have a look at it. You probably do not have the dwell times matched to the coil. Certain coils, like an MSD Blaster 2 require a LOT of dwell. The MSD Blaster 2 is a poor choice for an inductive ignition. They are designed for a CDI ignition and just don't have the correct properties to work well with an inductive ignition. The stock Nissan 280Z coil will put out more sparkenrgy than an MSD Blaster 2 coil,, unless you really crank up the dwell to the MSD coil. It is a very slow saturation coil when used on Inductive ignitions.

    Bosch makes a PW controlled IAC that looks to be easier to set up than many stepper motors. Used on early 90's golfs. They run any where from $35 to $100 on E-Bay https://www.ebay.com/itm/New-Idle-Air-Control-Valve-IAC-Speed-Stabilizer-VW-Volkswagen-Jetta-Golf-EuroVan-/351773015388

    OERs dripping inside barrels

    Well... seems the Needles and seats aren't sealing. Now you have to find the cause. Either some trash in the N&S, N&S gummed up or possible floats are " Heavy ". Nitryl floats can absorb gas with age and sometimes Brass floats get pinholes in them. Usually at solder seams. Checking float level may not uncover a " heavy " float or a slightly leaking N&S. Only way to teall is to weigh the floats with an accurate scale. Brass floats you can hear the gas sloshing about inside.
