Here is the Excel file I used to map my Fuel and ignition tables. I am sure some of you guys out there can get some use out of it. I recently had Mick from subzero Dyno my car. You can clearly see the fuel he took out of it at PFC load Value 15-16. The car was being retuned at 1.10bar. The Ignition points around 15-16 need to be trimmed at peak torque to reduce detenation. Did make 225kw tho. When the timing is retarded I think it will negate the extra boost and all I`ll end up with is a slight increase in mid range power only, probably actually loose some up top.

Your right on the money Steve, I only get near those figures with a healthy dose of octane booster and I still get a minor ping. I`m taking it down AIR for the next street meet. Fingers crossed I can get through another 6 passes.

Thanks boostd useful info.

I actually leaned out the fuel map at idle to try and reduce exhaust fumes (I don't have a cat fitted). Hunts a bit now (I took the AFM screens out also), but less likely to gas myself whilst idling in a semi-closed garage.

I'll drop my maps in for the RB26 and post here also.

Anyone else got RB26 maps?

Its Greg from base. What do you reckon try loading your figures into my car. Where could I go wrong. Our cars have the same mods virtually. Mine has only had one tune for an hour on a 43degree day. So there is nothing to loose. I am planning a turbo upgrade in the near future so it will have a retune then.

    • to fix the voltage drop issue I swapped out the old 150amp alternator which turns out is a brand known for having issues and replaced it with the black 180amp alternator beside it 
    • For anyone interested, the Way Back Machine has that Japanese website archived with pictures, etc: https://web.archive.org/web/20051023225805fw_/http://www.a31cefiro.com/air_con.htm "Simply swapping the wiring of the harness will not allow it to function properly. For the outdoor air sensor and sunlight sensor, disconnect the wiring connected to CN1-11 of the air conditioning harness from the harness and connect the sensor side wiring to earth. For the indoor air sensor, disconnect the wiring connected to CN2-3 of the air conditioning harness from the harness and connect the sensor side wiring to earth. The connector PIN numbers listed here are the genuine A31 PIN numbers. To avoid incorrect wiring, check with a tester before wiring. Also, disconnect the wiring in a location close to the sensor. The disconnected harness side wiring will not be used, so be sure to insulate it." Wish someone sold a conversion harness to just plug-and-play a Kouki 180sx digital climate control into C33/A31. I'm decent with wiring but feeling kinda lazy about taking this on. Edit: Did some more digging and found a helpful Minkara blog post about the conversion as well: https://minkara.carview.co.jp/userid/1831116/car/1360568/2284209/note.aspx "After installation is complete or the battery is replaced, you need to go into self-diagnosis mode and set the internal air recirculation. The way to do it is to "hold OFF with the key on for more than 5 seconds, set the number to 5, then press 卍→C." ↑↑↑It probably won't make sense unless you actually try it (・∀・)." Lol wtf

    • Well, yeah, the RB26 is definitely that far off the mark. From a pure technology point of view it is closer to the engines of the 60s than it is to the engines of the last 10 years. There is absolutely nothing special about an RB26 that wasn't present in engines going all the way back to the 60s, except probably the four valve head. The bottom end is just bog standard Japanese stuff. The head is nothing special. Celicas in the 70s were the same thing, in 4cyl 2 valve form. The ITBs are nothing special when you consider that the same Celicas had twin Solexes on them, and so had throttle plates in the exact same place. There's no variable valve timing, no variable inlet manifold, which even other RBs had either before the 26 came out or shortly afterward. The ECU is pretty rude and crude. The only things it has going for it are that the physical structure was pretty bloody tough for a mass produced engine, the twin-turbos and ITBs made for a bit of uniqueness against the competition (and even Toyota were ahead on the twin turbs thing, weren't they?) and the electronic controls and measuring devices (ie, AFMs, CAS, etc) were good enough to make it run well. Oh, and it sounds better than almost anything else, ever. The VR38 is absolutely halfway between the RB generation and the current generation, so it definitely has a massive increase in the sophistication of the electronics, allowing for a lot more dynamic optimisation of mapping. Then there's things like metal treatments and other coatings on things, adoption of variable cam stuff, and a bunch of other little improvements that mean it has to be a better thing than the RB26. But I otherwise agree with you that it is approximately the same thing as a 26. But, skip forward another 10 years from that engine and then the things that I mentioned in previous post come out to play. High compression, massively sophisticated computers, direct injection, clever measuring sensors, etc etc. They are the real difference between trying to make big power with a 26 and trying to make big power with a S/B50/54 (or whatever the preferred BMW engine of the week is).
