335i, Evo X, 996T, 997T, M3, M5, M6, RS6, C63, GTR are all potentials, I can't decide, but I'm ready to move on from the Evo. All polished up and going to pick the buyer up from the airport in an hour.

I want something fast, would prefer AWD and turbo(s), not too flashy or boy racer looking, handles as near to an Evo as possible but with much more refinement, and lastly that I can avoid dealers charging my *** off for $$$$$ for maintenance. Nothing ticks all the boxes. Budget doesn't matter too much as long as I feel I'm getting value for money.

They don't make a 335ix in right hand drive, otherwise I'd jump on that. With a tune that would be everything I want. As it is, a 335i and some winter tyres might do nicely.

John, has your Evo gone?

Can't believe you are selling...

Get the GTR, I'll join you next year when you've cracked some code!

w00t to bring this thread back on topic I think i finally have my speed density settings nailed down. It appears it was a combination of injector latency and map vs load settings that were throwing off my tuning for the open loop area. I still need to give this girl a long test drive which i will do on my way home.

I'm sorry to go off topic too, but does this mean you will be leaving this forum for good John? And stopping work on speed density/live tune?

On topic kind of, I want to set my car up on speed density soon but I need to get my new wheels installed first. As I set mine up I'll write a how-to if no one else does by the time I do.

Yes, Evo sold. I think the ECU work is more developed than any of us could have imagined. I don't expect I'll be doing any new developments, but I'll still get involved in special Evo projects, I'm excited about the GT42 stock ECU build

Oracle, GTR is tempting now the maintenance schedules are rumoured to be more sensible.

Glad you're progressing RoadSpike.

Off topic - sorry guys

John, I agree the OEM ecu work went beyond all our expectations and the SD work you did Fantastic

My head will be back on the weekend, so I guess another week left then you'll be hearing from me more

Met some old pals who are into their GTR's, alot of stuff I can see going on there. If it was me, for the money new buys GTR or second-hand 997 turbo - no brainer.

Does anyone know the definition for this for 96530006? I have a rough lean spike with throttle transients that I would love to get rid of.

Try this (completely untested):

Nevermind, see l2r's post above mine.

You beat me to it.

Edit: you know, I had 6aa0 down originally for the x-axis on "Accel Enrich Base vs. Engine Temp", but looking it up just now, I came up with 69be (which also looks correct). Do you know offhand which one is right?

At least we agree.

I would have to look into the ROM to be sure, but I think what I have is right. I wouldn't be shocked if it weren't though. Actually, I'm not that good at disassembly, and the correct axes is always the hardest part. I think someone explained it to me once, but I forgot already or maybe didn't understand completely at the time.

Edit: Looking into the ROM more, it looks like 69be may be correct, since I see the same reference to a variable as in the same map. But, again, I'm not sure why I came up with 6aa0 instead. Maybe a disassembler can give us a recap on how to determine the correct axis location.

How does this table work?

<table name="Asynch_VS_TPSDELTA" category="Fuel" address="38a2" type="2D" level="1" scaling="uint8">
<table name="X" type="Static Y Axis" elements="9">
<data>0</data>
<data>1</data>
<data>2</data>
<data>3</data>
<data>4</data>
<data>5</data>
<data>6</data>
<data>7</data>
<data>8</data>
</table>

What is 1,2,3,4,5,6,7,8? The values that I have in this table are 16-34 for starters. I need to get rid of this lean spike on tip in with SD, but I'm not sure how to work with this table.

Thank you!
