Re: GPS Sensors

GPS/Accel data transmitted and recorded via my Plex dash and the Syvecs ecu really takes up negligible memory. Likewise VBox datalogs of GPS data take up miniscule amounts of memory Memory is in no way an issue even with a basic S6 with a paltry 1MB of memory. Neglible memory? Quick math. GGA - Glo...

Re: GPS Sensors

And will it transmit the data to the ecu via CAN ? It depends... Transmitting over CAN is not the problem (adds 20-50 USD) - to ECU memory it certainly might be, as; - there is no 'standard' nor open communication protocol/documented methology to input this kind of 'external' rather generic data - ...

Re: GPS Sensors

Nowadays, one can build a suitable 50 Hz GPS receiver under 100 USD.

Re: Closed loop fuel pump setup

just a quick question and I'm sure this is gonna sound dumb but the fuel control pwm out put is a positive feed ? I'm getting the circuit built for the negative side of the pump and the guy making it asked me to make sure of the feed is + or - Usually feed is positive and 'constant' - so pulsing is...

Re: Closed loop fuel pump setup

Racetronix sell some insulated connectors for passing through the tank... I think that 'forget those', because no proper information is given - instead they hide it. Much better solution is to use proper FTC connector, for example from Deutsch Autosport series. http://www.deutsch.net/en/browse-prod...

Sensor heater would draw max. 3 amps when cold and 1 amps when hot. Maximum pumping current is few milliamps.

Re: UEGO

In newer stock WRX exhaust system, front oxygen sensor is located before turbocharger.

Re: UEGO

On the contrary. Nowadays OEM's tend to run their turbocharged engines, close to lambda one - under full power situations also. Sensors do have pressure and temperature dependency, but OEM's do model their installations, so the pressure- and possible temperature variations also are taken into accoun...

Re: anti lag

Those (Subaru and Peugeot) systems definitely, are NOT EGR system's in any way. But effective auxiliary air systems - you can't get enough air (air/fuel mixture) using idle speed air valve to keep up turbo revolutions.

Re: anti lag

KISS... Keep it simple stupid. No diffucer, just plain pipes from auxiliary air valve. Air entrance from cold side of IC and some ecu control strategy. Picture from 2002 Peugeot 206 WRC. Cold side feed, helps to prolong ALS - at least few milliseconds longer, before melt down.
