I'm Automotive Engineering student from Finland.
I were developing four-cylinder BMW M10 2.0 '77 turbo engine as my engineering/diploma work, but I have changed my work to Honda D16Z6 SOHC-VTEC All-Motor project. Reasons for this are too high costs for a student, and I definately need a new (and ofcourse better and more powerful) engine to my daily driver Civic.
I'm using GenBoard with my Honda, and now it's running on my old D15B2 (1.5 16V SOHC) engine with ITBs.
Pure AlphaN, WBO2 etc now working excellently! Engine runs damn smooth in ~any conditions, EGO correction works etc.
That AlphaN is very easy and straightforward to tune.
I also tried AlphaN blending first, but that doesn't work for NA engine with ITBs, it's only meant for smoothing idle with aggressive cams. config13 bit 2 has to be enabled via keyboard or config.txt to get AlphaN working! MegaTune doesn't have an option for changing it! I had some serious problems trying to get engine working without it first (and blending enabled in MT; It just doesn't work at all).
Check my MembersPage/JanneMantyla/PictureGallery ! WARNING! lots of high-quality pictures on same page! Should I do this somehow other way?
D16Z6 Engine construction
- Bore 75mm, stroke 90mm
- Honda PM7 high dome pistons, 12:1 compression ratio
- ARP head studs, rod, flywheel and pressure plate bolts
- Reshaped stock valves (30/26mm)
- [Crower Stage 3] cam, Crower valvesprings and Ti-retainers
- 42mm ITB setup. Honda CBR954RR throttlebodies and injectors (hi-z), my own designed/made aluminum manifold. Intake total lenght 230mm.
- My own design 4-1 anti-reversion header(lenght 660mm/26", merged collector), 2.5" exhaust.
- ACT XTSS clutch Xtreme pressure plate, performance organic disc
- ACT [XACT Prolite] 3,8kg / 8.4lbs flywheel

D16Z6 sensors etc
- Original Denso IAT/CLT sensors (values equals Bosch)
- Original TPS and MAP. MAP seems to be 180kPa type (I've ~1kPa ofset) and is working perfectly.
- Maybe VAG 1.8t 20V active COPs. These are cheap, and suits fine to Honda head. Another alternative could be CBR600 F4i passive COPs. Bosch wastedspark is powerful, but not as sophisticated, and needs ignition wires as expensive as VAG COPs.
- Honeywell 1GT101DC Hall-sensor at crank. One trigger pulse/event. Maybe 4-1 or 12-1 wheel decoder in future
- Propably some camtrigger. Original(D15) distributor has two VR-sensors on it. I don't have D16 dizzy, they have three sensors, one (CYL sensor) gives one pulse for every two cam revolutions, so it would be good as is, but I'm not gonna buy expensive dizzy that I'm really not needing. I think I'll just install a Hall-sensor to old D15 dizzy.
- VTEC relay output. I think I'll use one MiscOut for this. Honda PGM-FI uses rpm, tps/map and clt as a parameters for this function, seems that I can't get clt but who cares, just remember not to use VTEC (rev past 5krpm) with cold engine (stupid anyway)
- Bosch LSU-4 WideBand sensor
- Blue 4x20 LCD
- EGT K-type thermocouple
Gonna upload my mcd.txt and mct.txt soon.
