I'm getting closer to sva and I need the set up the MotaLeira to pass emissions and to tune it for "normal" road use.
I have a Power Commander with LCD screen and I have a wide band Lambda LC-1 and XD-16 gauge. The LCD screen will allow me to switch maps easily.
Martin Bell kindly sent me an "sva" map a while ago as a starting point for my set up. The main difference is I am using the stock airbox
and the map was set up for a piper foam filter.
I expect to have to change the map as my airbox alone will have a difference.
Will I be able to adjust my emissions purely using the PC & LC-1 on their own or do I still need an emissions tester?
Although 14:7:1 is the goal for a road car I have heard that 15 is better for the R1, I'm not sure.
Will running on an sva map damage the engine?
I know that it only has to be different at 3000 rpm and at idle for the test.
A bit confused at the moment
I've never tuned an engine "electronically" before
The only areas of the map that matter for SVA are idle@zero throttle and 2500-3000@zero/2% throttle. The rest can be set anyway you like and
won't effect the test. Having those to bits set to lambda1 at closed throttle will also have no effect on the running or reliability.

So using the LC-1/XD-16 will be enough to find this?
I have a SVA map which the lads at mac did for our engine for SVA. Engine was on a stock airbox with Mac's exhaust which had a cat in.
As far as I can remember the adjustments were based on a standard R1 power commander map & adjusted based on emmisions at 3000 rpm. You are
welcome to have the map to compare with what you already have.
They adjusted the map on a PC based on exhaust emmisions.
We trailered the car to the SVA & once passed we removed the power commander & ran the engine on the R1 ecu until setting up the power
commander on a rolling road.
U2U me with your email address if you want the map.
That sounds very close to my set up. U2U in progress!

My CAT doesn't take long to get hot, it is just after the point where the manifold pipes meet.
Hopefully I will have 3-4 maps to take with me for sva, so one of them should be close!
Michael, thanks for the map.
I compared it to the one I had and it looks a lot better.
Especially in the 2500-3500 range.
Once I have the O ring for my fuel pump leak sorted, I'll give it a blast and check it on my XD-16 gauge.
I'm pretty sure that it will only need minor tweaking (if any)
Cheers Martin
