You could use it to tune an existing ECU if you have the right software, but to run your engine from a laptop, not a good idea.

Engine management requires a real time operating system to control fuel injectors etc and read input signals. Windows is a non-deterministic operating system which means interupt latency is not guaranteed. Even Embedded versions of windows can be called soft real time at best. This means it responds to imputs when its ready, not when you need it to. Also you have to contend with the blue screen of death etc. If you use linux, it is better but it is still not a hard real time operating system.

Hypothetically if you did get all the software sorted out and had a hard real time operating system and the appropriate engine management software installed you still have the problem of having the required interfaces such as reading all the input signals and being able to drive outputs such as fuel injectors. So an external interface would be required.

The laptop is also not made to run in that environment full time. The hard drive would fail and you would probably suffer random lockups from internal problems caused by the continuous vibration and g-forces.

if you obtain a conzult cable from PLMS Developments you can read your ECU all fine, but that doesn not do tuning.. only part i have heard of really for hand on tuning is hand controller for Power FC.

I am running the conzult cable on a r32 rb25 and it works all fine, i can read everything from the ECU, turn off cyclinder, increase/decrease timing but very limited options.

I have tried a few programs but they basically all the same, but would never think about running a full engine management system off a laptop as GTRman has said, would not be worth it.

Can you re turn the original ECU's? i know yoshi would be able to do these i think.

Having 12 guages on a laptop is kinda cool looking tho. haha :cheers:

    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go
