Just thought I'd mention that I have got Launch control working on the RNN14 stock ECU in the UK here too. Tried it yesterday on a 400hp GTi-R nearly ripped my head of on the launch

Affects fuel cut on over run, cant see it affecting timing.

Yep may have been that too. In fact probably more likely so.

Couldn't agree more. I had major issues recently only with really careful logging and producing graphs did I realise that the engine wasn't reading load correctly, it turned out the 'new' Nissan afm was in fact a fake Chinese unit. Exactly the same as skyline_stu posted above. AVOID AT ALL COSTS THE...

Flat is often good, not bad. I mapped a SR20VE today. It has an almost totally flat torque curve. On the road it felt not very exciting as it was so smooth, but there was the most area under the torque curve this way, and hence most available power at any given point as you can see here: http://www....

Just also thought check that the maf voltage engine off is about 0.5v or so.

That looks like a pretty retarded light load area on that map. Say in the load areas between 30-63. Although you will not be able to accurately map that on the road since you'll never likely get knock (where there is not enough boost made) and your arse dyno (!) will not notice 2-3 hp in those areas...

That's great cheers Adam, I'll see if i can find you some pics. Its a turbo conversion the customer carried out and one I have been working with for a few years. Started of as a perfectly reliable 1.4 turbo then he got the itch for more power killed a few engines and ended up with a 1.6 producing so...

That would be my ideal solution, but often the cars aren't with me long and getting it on the ramp to do this kind of work can in reality take a couple of hours. I usually ask that the owner would get them fitted before they arrive, makes my life easier at least!

Maf voltage looks way to high. What maf and where is it in the pipework in relation to the turbo, and do you have a dump valve or similar that is not a dual valve type that may be open at idle?

Interesting so only Europe had the 5 slit GA/CG timing wheel? skyline_stu and Adam, just to be absolutely clear this distributor came from an Aus N15 GA16DE engine? I will need to change the whole distributor, not just the wheel as those have a two wire output where as the UK GA16 N15 has a single o...

old engine never had any faults at all apart from datascan picking up the fueltemp problems but running and driving I couldn't tell it had a different ecu. fuel temp affects starting the car with the Z32 on RB25. you need to use a resistor 2K ohms from memory between fuel temp line and ground to ma...

Yeah to be honest I have had no calls for this for ages then I have had three enquiries in the last month

Love the new changes.. I had people saying to me they dont need to buy it as they can keep reloading it, I found this most annoying. Re Fordys comments, computers are excessively powerful these days. Plenty enough and more from even the most basic machine you can buy. Even my 9 year old laptop will ...

Feel free to get in touch we me if you have any questions Andy, I've been getting asked a lot about these recently.
