#1g dsm data logger software code

If something goes wrong, the ECU will still throw a CEL, but you won't be able to pull the codes from it.

To make room for all the new tables and functionality, a lot of the self-diagnostic code has been removed. This will greatly help tuning if you don't have a datalogger or wideband O2 sensor. '0' on the gauge (in the middle) corresponds to roughly 15 knock sum, if I remember correctly. When there's zero knock, the needle will stay at the bottom of the gauge. This is much more useful anyway, as everyone at this point should have a real boost gauge. The factory boost gauge will now work as a knock gauge.

Speed density-based air metering can't do that, and that means we have lots of tuning ahead of us.

Our stock air metering system measures the air entering the engine directly, and can compensate happily for changes in exhaust, cams, headwork, or anything else we do to it.

This means we have to make a nice big VE table, with 256 different load points, and this VE table will need to be retuned with every mod you make. Unlike the volume or mass airflow measuring methods used by our Karmann airflow meter or a hot-wire airflow meter, we need to know exactly how much air our engine can aspirate at any given rpm and intake manifold pressure. Tuning is a pain, especially by yourself. Superior in this regard to both 1g MAS, 2g MAS, and MAFT setups. However, they will no longer throw your A/F ratios or timing off. Of course, you still want to avoid boost leaks, as they slow your turbo spool, limit your max boost/power, create more intake charge heat, and shorten your turbo's life. Your BOV can leak, your TB shaft seals can leak, your fuel injector seals can leak, your intercooler hoses can pop off even, and as far as drivability is concerned, the car will run great. Boost leaks no longer matter, as far as your fuel system is concerned. No more clouds of black smoke and bogging from running rich when you vent your BOV It may sound daunting, and expensive, but it really isn't when you think about the cost of an SAFC and upgrading to a 2g MAS, or MAFT + GM MAF. If you have an EPROM ECU, you can convert your ECU to speed density, using a MAP sensor to replace your 1g MAS. So, you're finally tired of hunting down boost leaks and dealing with that nonlinear, restrictive, easily overrun karmann vortex 1g airflow meter, huh?
