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:

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
