Lotek 3 gauge pod in a V70 - Pics?

J_Guynn · Post by **J_Guynn** » 13 Apr 2005, 08:15

I am considering adding boost, oil pressure, and voltage gauges to the 98 V70 I just bought but I'd like to see at least one pic of the Lotek pod before I decide that's the way to go.

Does anyone have pictures and how well does it match the tan interior?

There are several people over on the VS Forum that have done 3 guage pods. You may want to search around there. I plan on doing a guage pod eventually, but probably two pod. Boost and wideband o2.

Oh, and where's Missouri City, TX?

W8T, what's wideband o2?

^^^ The item on the right is the wideband o2. It's an A/F meter than can actually be useful. Many people have narrowband A/F meters, but those are really useless. With the wideband, you can determine with incredible accuracy, your Air/Fuel ratio, which can be used to determine a wealth of information. Basically, the ECU determines a car's performance based on a ton of signal inputs from all sorts of places. The two most important determiners of performance and optimal engine efficiency are the A/F ratio and the engine's timing (for which the info is gathered by the cam position sensor, and engine speed sensor, knock sensors), usually measured in degrees advanced or retarded. Perfect A/F ratio, also called Stoich, is technically a ratio of 14.7 parts air to 1 part fuel, more commonly seen as 14.7:1. Every engine has an ideal A/F ration for every engine speed. If the A/F ratio becomes too rich with fuel, the car will experience poor gas mileage, high fuel-oil dilution, and possibly washed cylinder walls. If the A/F ratio becomes too lean (not enough fuel), detonation can occur before the knock sensors are able to retard timing. A lean A/F generally leads to higher internal engine temperatures as well and as we all know, heat destroys. On the turbocharged 2.3L Volvo engine (B5234FT), you should see A/F ratios of around 14 when cruising around town, not slamming on the gas and making the turbo kick in. When the turbo kicks in, there is a much higher demand for fuel due to higher cylinder compression. An ideal A/F ratio for these engines under full boost would be 12.0 to 12.5. But then you might say, I thought ideal A/F ratio is 14.7. Well, you'd be right, sort of. But here's why it doesn't work like that. When things are compressed, they become heated. As we all know, some things heat faster than others. This characteristic of an element is called its relative heat. Air heats much more quickly than fuel. So... more fuel must be supplied to prevent the present fuel and now compressed air mixture in the cylinder from igniting too early. This is why higher octane fuel allows you to run more boost. It is more resistant to pre-ignition.

Any questions?

Thanks for the pointer to the other forum, I'll go spend some time over there.

Missouri City is on the SouthWest side of Houston, between Houston and Sugarland. Oddly enough my V70 came from the Carmax in Plano.

The above post from Guest is from me, I didn't realize I wasn't logged in.

Interesting, thanks W8T.

Sorry for the off-topic question, J.
