Update : I had been fighting an erratic wideband on the rear collector -cylinders 4-6. Well it turns out I still had a leak at the collector which is before the O2 sensors - dammit . This is a Z story header and collector . The collector pipe was modified for my exhaust and I thought I had the flange true , but it still leaked . This time around I eliminated the gasket all together and used Red Loctite only . At the same time I had a new O2 sensor installed since I was that deep into it . I DID see evidence of a leak but changed the sensor anyways . FIXED! This change helped so much with the tune and you could hear it ! I was able to get the banks to harmonize much better with AFR’s and sound . This helped to mitigate the drone I was getting at low rpm cruise . I thought this would also fix an issue I’ve seen on every intake I’ve used where the AFR’s between the two O2 sensors would be different during high vacuum running - light cruise . Megasquirt didn’t seem to be able to compensate in those scenarios though I had two separate O2 sensors dividing the banks . I ended up going into the injector trims and adding fuel to 1-3 since they ran really lean under high vacuum . Maybe they suck all the air out of the plenum before it reaches the last 3 cylinders . I added almost 20% to 1-3 . At this point the AFR’s evened up and you could feel and hear the difference . This is probably the best I’ve had my L running . Happy guy right now

Spent today packing up orders and only 5 outstanding. Looking forward to wrapping these all up once I work through the technical issues on these ones. 1. 7d2jz 2. MAG58 - PAID - SHIPPED 3.

I miss the old days of the forums. I would not call it a skill, but just some practice over the years and figuring out what works, and what not to do, usually the hard way. So dont be afraid to try and practice if you enjoy this sort of thing. Its not great work, but good enough to satify myself. I have a friend who welds, he has talant

I’ve been using Megasquirt 3x on my 3.2 for a while now . I had a knock sensor module installed on my X board . For some reason I can’t get it to work . I have a feeling there is a defect in the pin out during install . I’m not good enough to troubleshot bad install of a module and I’ve been reading about the usefulness of a cheap audio version that could made for 50$ . Background - I had to tear down my 3.2 because I had remove the crank to clean up the snout from a bad balancer . When I popped out #6 I found a broken top ring and evidence of detonation . Admittedly I was aggressive with timing and it bit me . There were no signs of the broken ring and the pulled 225 rwhp on the dyno . In fact that cylinder showed the highest CR = 220 psi This engine trans package is very noisy . I had straight cut gears and Kameari chain tensioner and a loud exhaust . I thought I heard ping around 4300 and attributed it to a rattling shifter - oops . # 6 was the only cylinder with any damage . I also pulled coolant from #6 at the head with a bypass to help mitigate problems . This time around I want to make sure this doesn’t happen again . I followed this you tube video. i was skeptical but it really works well. I drilled a hole above the freeze plug around 5&6 . Plenty of met there and there is a flat boss area for the sensor to sit flat against the block . You can hear the valve train clearly but you can also hear the ping clearly . I ended up pulling 4 degrees out of total timing on 93 octane . Megasquirt 3 allows for individual spark trim and I am going to try and isolate the issue to number 6 if that’s the case . Anyways - it’s not as good as real time retard available on ECU’s , but it is very effective to show some limits .

Bringing this back from the dead! After my dyno session where you could see significant blow-by coming from the valve cover, the car progressively started producing blue smoke from the exhaust. I don't recall the exact timeline now, but around mid-2016 Flatblack helped me pull and disassemble the engine. We discovered two pistons with broken skirts, and one piston with broken ringlands. My head gasket was also hanging on by a thread, with very elongated bores. Since then other life priorities took precedence, and the car was basically untouched for 7 years. Mid 2023 I finally took the car in for paint, and got it back in October. Meanwhile I had the block cleaned up, found some used pistons, performed the coolant bypass mod on my P90 head, did the 240z tail light conversation, and last month finished reassembling the longblock. Sometime between 2013 and 2016 Flatblack sold his 280z, so we traded flywheel and clutch setups so I'd have more torque headroom. At some point his flywheel dowels went missing, so I'm waiting on replacements to get the engine stabbed back in and broken in over the next few weeks. Once I have everything complete, I'll post some reveal pictures of the new look! Short term I need to get a rollbar, some performance seats, and harnesses put in the car. I'll also need to get my MS2/Extra upgraded to the latest version, and apparently be a little more conservative with my tune. From there, I'll likely pursue installing the Snow Performance meth kit I've been sitting on for a decade, follow-through with the 280zx CV swap with the weld on adapters, upgrade injectors and swap to running E85, and look at swapping to a properly sized modern turbo to support my original 400whp goal.

My shirts arrived today, with the wait - huge thanks to Ryan for tackling this big job that benefits all of us and HybridZ! It was difficult to choose amongst all of the colors but very happy with my choices!
