Location: Jelling, Denmark		hello. For diagnostics purposes and needle profiling without visiting a rolling road and paying for that I am looking at buying something like a "Spartan 2" or and "ALM-board" which are both controllers that convert a wideband lambda signal to a voltage of of 1-5 which will be easy to log to a file using an arduino and a pc. the goal is to be able to log AFR at RPM to a file on the pc.
Do you have any recommendation or suggestions?

Location: Letchworth/Basildon		The AEM unit is around £150 and includes the gauge. They have become so cheap now that i wouldn't bother with a kit.

If you do put something together yourself, try to find something that uses the latest LSU4.9 sensor rather than the old 4.3. Unless you go for an NTK of course

Location: Jelling, Denmark		Thanks for the info. I am going to use a bosch 4.9 sensor yes.
the primary thing i want to achieve is logging of the data to the pc so that i can use it for drawing a graph and selecting needle profile.

Location: Tebworth		I built a JAW from 14point7 - worked very well. Currently running a techedge one as it came up at the right price and I could use it with a standard gauge in place of my clock on the TF.

I have been reading about the techedge one and its very nice with the extra inputs. it has a lot of nice features build in.
