  1. For a true test of ride comfort. drive your Z car from Blaine Washington to Seattle on the I5. Rough concrete with expansion joints for most of the way. Just came back from SOVREN Vintage races at Pacific Raceways. My 76 280Z has front DIY TT3 Coil overs, 250 lb/in Eibachs and Koni Sport Yellow shocks . Rear is " temporarily " Eibach Pro springs ( Don't know rate but they are pretty soft ) with KYB gas struts. Edit: Forgot front Camber plates . Rear temporarily has the front Nissan top insulators installed to lower rear. Will be getting Camber plates as well. Front was very comfortable on the street and on the I5 . I5 is brutal on cars with too stiff of springs and shocks.. Koni's are on setting 1 at the moment, but I will probably be turning them up to a 1.5 or 2. Rear shocks and springs are comfortable, but too soft. I'll probably go to 225 or 250lb/in on the rear as well with Koni Yellow sports. TT3 Coil over kit. Soft rear springs show up on track days when I get a bit too much rear squat exiting corners. 1.125" ST front Bar and 0.875" ST Rear Bar. Tires are Continental Extreme Contact DW in a 225/50x16" . The taller sidewall really soaks up bumps and expansion joints well. Very good Traction in Dry and Wet. Wet traction is important in the PNW. I may switch to a 225/45x16 in the Future. The Conti's are just a tad too Tall at 24.9". Considering amount that car is lowered. I'm using new stock rubber bushings all around for noise isolation and comfort. The stock rubber LCA bushings are far better than Poly. Monoballs transmit too much road noise for " my personal " street car. Been down that Road before. This is just going to be a nice, quiet GT Touring Car. As you get older you appreciate comfort more and more. Picture of Camber Plates used for front and rear:
  2. Like John M, I also used a Non-Booster equipped Road Race 240Z back in the Day. You have to eliminate the Booster. Make a Custom length Pushrod. Depending on you Pedal effort, you may want to relocate the Clevis Pin hole in the Brake pedal upwards a bit to change the Pedal ratio. About 0.750" to 1.0" is enough. We used a standard 7/8" Master on our ICSCC D-Prod Z . Worked out very well. Good modulation with proper setup.
  3. Getting my own Haltech E11 dialed in. Very powerful ECU ( Full Seq Fuel on a V12 and wasted spark with V12 ) , but old school. No VE Calculation. Uses Raw Injection Time... which took a bit of head scratching to work out. But it's all just Mathematical calculations in the end. Kinda like using DOS... but it works just fine. Think it's an Ozzie thing ( Haltech is Australian based ) as even the latest Hatech's still use Raw Injection Time... plus VE Calculation and Mass Airflow calculation methods of course. Nice to have choice. Dialed it in by driving the same 100 Mile Loop over and over. Data Logging the whole way. First 200 miles I used a Co-driver, and just worked the Tuning software in Real Time as we drove. After 200 miles, the Tune was good enough that I could just go Solo and DataLog. After 500 miles of Data Logging , Tune was good enough that I was pulling Cruise AFR at 15.0 to 15.5 ( Getting 30+ MPG ) and 12.5 to 13.5 at WOT ( Normally aspirated ). I've since been playing with fiddly little stuff such as Hot Start enrichment and Cruise AE tip-in values. Hot and Cold starts are now instant. Way better than stock Nissan ECU ( 75 280Z NA with engine Mods ) . Hoping to get on a private Race Teams Dyno soon. Dyna-Pak Hub dyno soon. Waiting on a couple of Ford GT's so a Tuner friend can Tune those and then I'll pop the 280Z on the Hub Dyno at the end of the day. Hub Dyno's are so cool.
  4. You can compare the different Haltech ECU's here: https://www.haltech.com/product-overviews/ They also have Videos and a comparison chart. The Elite 1000 has a few more advanced I/O features than the Elite 750, but not as many Inj drivers and coil drivers. The 750 is also cheaper than the 1000 . There is a trade-off between more features or more drivers. There are comparison Charts at Haltech. You may not need the Launch control, Traction Control or Knock control. ( Since the L28 has no knock sensors )
  5. Elite 1000 only has 4 Ignition Drivers and 4 Injection drivers. I would go with the Elite 750. It is purpose built for 6 cylinder engine and will do everything you need. Go to the Haltech Group on FB. Look up Claudio Taverus Peynado . He used to work for Haltech and has his own shop now. He is a Haltech distributor. https://www.facebook.com/groups/haltechtuningandtips/ https://www.haltech.com/product-overviews/
  6. 1: What are you using for Spec Torque? FSM says 87 to 116 Ft Lbs. 87 ft/lbs is NOT enough. Use a new bolt and go to Maximum Torque. Or even a Tad Over. Threads inside and out MUST be cleaned and lubricated with either oil or Loctite. Dirty threads will result in bolt being under torqued and it will not reach it's Stretch or " Plastic " specification. 2: Do you have the correct length Factory bolt with factory thick washer? Washer is very important. Threads will bottom out in crank if you use the wrong washer. 3: Buy a new Factory Nissan bolt. Bolt may have stretched beyond it's " Plastic " state. Once that happens they will not maintain torque. 4: Is the Harmonic balancer stock? Some of the aftermarket hubs have a thicker hub and require a longer crank bolt. Found that out the hard way on a Tilton damper. Damper loosened and bent the crank snout. It was a Tilton crank... so BIG $$$$$ 5: What type of Loctite are you using> Medium strength ( Blue ) is not good enough. You need the Red high Strength Loctite 462. Just a couple of drops. Make sure threads are clean. Inside of crank and on bolt. Use Brake Clean. Really, on a street engine, the Loctite should not be necessary. I would suspect that the Bolt is " Stretchy " , threads may be worn or you are using the wrong bolt and washer. These things should not back out... unless you are constantly twisting over 8,000 RPM. One other thing I just thought of. If the damper came loose onec... you may have bent the snout of the crank. Check the radial runout with a dial indicator. I'll have to double check.. but I think the limit is .002" . If snout is bent it will setup vibrations that will keep loosening the damper
  7. Link G4+ Storm is also a good alternative. But the Elite 750 is a very nice ECU. I've tuned both... which is one reason I'm getting away from tuning a different " Build it yourself " brand. The difference in quality of a " REAL " ECU is amazing. Haltech and Link just work properly out of the box. Period.
  8. Haltech Elite 750. One of Health's entry level ECU's, but it is purpose built for 6 cylinder engine. Comes with 6 logic coil drivers and 6 High or Low Z injectors drivers. The Low Z injector drivers are true Peak and Hold drivers. Not the cheaper, slower and less accurate PWM Current limiting drivers found on some popular " Build it yourself " ECU's. For a single Ignition coil you will need an external power amplifier. 0v to 5v logic level. The Nissan PRW-2 module is a perfect match. You can find them used for about $10 on E-bay. The Nissan OEM PRW-2 modules are powerful and last forever. Used original Nissan Modules are preferred over Chinea manufactured crappola. Like OEM GM LS-2 coils over aftermarket clones.
  9. Looks like your Spark A ( Cylinders 1 and 6 ) coil pack isn't firing for some reason. Or is misfiring. Misfires will always show Lean on an O2 meter... even though plugs are wet with fuel. Check your Ignition settings for the Quadspark. Pay attention to proper grounding. https://www.diyautotune.com/support/tech/hardware/quadspark-ignition/megasquirt/
  10. One of the interesting things the Audi BT guys are doing is putting a 4" expansion section on the downpipe. This really results in a drop in Exhaust back pressure. Quicker spool and higher WHP. They are transverse mount, so limited by space. But even a shortish ( 12" ) expansion pipe made a noticeable difference. I suspect a 4" downpipe on an L-6 then taper to 3" or 3.5" exhaust would certainly help.
  11. Finally got my 280Z sorted and took it out for an Initial 100 mile Road Tuning session. Went quite well. Ancient Haltech E11 with none of the fancy Tuning aids is certainly a challenge to Tune. But I like a challenge. Good and very powerful ECU... just very basic software. Raw Injector Timing tuning. No VE tables.. Slide Rule and abacus stuff... but it works. What you see is what you get. It's kind of like DOS compared to Windows XP. New stuff is just so much easier... Now to enjoy some cruising on week ends.
  12. Run the MS3 ECU main grounds to the engine. ( As per MS Extra Hardware manual ) . Intake manifold or cylinder head preferred. " Star Ground " the Speed Hut gauges to the same point on the engine as MS ECU ground. Voila. No voltage potential difference. Gauges can be grounded to engine, battery or Chassis. When running as a stand alone gauge it doesn't matter where you ground the gauge. But when tied into an ECU they need to be on the same ground plane. Chassis grounds on 40+ year old Vintage cars are the worst place to ground ECU's and other engine devices. .
  13. Just want to thank all of my past customers and current customers for their support. But I am taking an indefinite break from Remote Tuning. It's turned out to be too successful, so much that I no longer have time for my own projects. I haven't driven worked on my own 280Z in Ages, and I find I'm spending far too many hours staring at Computer screens. So I'm going to take an extended break and enjoy life . Time to travel and enjoy my retirement. I'll be finishing off Tunes and details with past and current customers. But I will not be taking on any new customers in the foreseeable future:. Thank you all for your support. Richard Boyk

    Just thinking out loud here. You may ask... " But why would Steve's ignitionbe OK at WOT but not at at low RPM's? " Well, you have to look at Steve's tune and engine combo to understand why. Steve's engine is NA. That makes a big difference. At WOT it is actually easier to fire the plugs than at low loads. WOT has richer mixtures that are easier to fire off than lean mixtures. Steve is also able to run very Lean low speed and Cruise AFR's due to the big spark energy from the GM coils. I believe his last table had a low RPM and Cruise range AFR at 15.0 to one. That's perfectly acceptable with big spark energy. And I believe that Steve is running NGK BPR6ES-11 plugs with a 1.1mm or .041" gap. The combination of Lean mixture ( raises Voltage required to initiate spark ) and wider plug gaps raised the spark plug firing point to more than the damaged insulation in the GM leads could handle. This created a lot of EMI and Triggered the Anti Stall/Auto discharge feature on the GM coils. Thus the low speed misfire. I'm betting it would also be worse on rainy days if Steve took it out in the rain If it was a Turbo car, the leaking plug leads would have been easier to identify ( You had to look at them very closely to see the damage ). Boost raises ignition energy well above what you need with a NA engine at WOT. Magnacore has some excellent articles on HT Lead damage and effects. It doesn't take much to cause a problem.
