SDS EM-4F with Data Logging

Recommended Posts

i had SDS on a previous engine. If i still had it and that option became available i would have upgraded in a second. Data logging when tuning is a must in my book!!! you would have to have a wide band in put to make it work right.



I have the datalogging chip. It's pretty limited. It only records the AFR (providing you have an AFR meter - preferably wideband) on the RPM map. But it can be handy for doing some quick tuning without a laptop. Keep in mind that because it only records on the RPM map, if you have a turbocharged engine, you won't know if the RPM or Manifold pressure map needs to be changed while building boost. Once you're at a steady boost level, you will know if it's the RPM map that needs adjusting.


For more detailed datalogging, I got a Techedge Wideband 02 meter which can log up to six channels. I just tapped into the SDS signals I wanted to monitor (RPM, manifold pressure, throttle position, and air temp so far). This made all the difference in the wold.

Nigel, the URL brings up an Australian site. Do you have to order from them or can this be purchased in North America / Canada? Thanks for the information.


I'm not aware of any North American distributors. They do ship internationally though. I bought one of their DIY kits (I'm an electronics tech) about 5 years ago and it's been working fine. A lot of other wideband products have come on the market since then. There may be better options now, but I'm happy with the Tech Edge product.
