This is what I was after

http://wbo2.com/lsu/cases/C3C4-side.jpg This might be familiar to you already, but I just come up with this. The larger is the LSU 4.2. The difference is huge. Which you think will act faster in heater controller wise in variable conditions where temperature fluctuations can be several hundred degr...

Real jobs are boring

The same goes for the rest of wbo2 manufacturers too... Except the ALM, right? :-p antonmies, is finland flat? Do you have no trailers there? There are many ways to stop a car accelerating and using the brakes is probably the worst. If you tried to use only the brakes and they were biased correctly...

My turn! Have you ever road tuned a car? Hell, have you ever driven a car? You're making a fool of yourself. Send me one of your units and when I get a chance I'll side by side it with Alan's stuff. I bet you don't have the balls. Fred. You need a fairly heavy class big brake kit to give some 600hp...

Utter rubbish. Best value is most features/highest quality at lowest relative price. Some very expensive things are excellent value, IF you can afford them. You fail to understand the word value. IE, (cheap != good value) = true... Perhaps English isn't your first language? You're right it isn't, m...

May the best value wideband controller win!

Fixed. May the most reputable seller with the best service and best value product win.

Fred.

Best value consists of compromises as they must be feature packed at low cost and to do the features properly, it won't be in the best value zone anymore.

The only pro the 4.9 has over the 4.2 is that the nermest cell resistance is 300ohms @ 750C, the 4.2 is 80hms @ 750C. This means you can more precisely control the temperature of the sensor. Both have the same lambda range and the same accuracy. The 4.2 has larger holes for gas to enter, so it is a...
