Datalogger on ECU

Oct 9th, 2002, 14:57

Does anyone use a Datalogger attached to their ECU and which type ?

More specifically are 1998 S40 T4 ECU's OBDII compatible and can I connect to it ?

I'm looking into buying the PalmOS Pocketlogger ($155) but it only supports OBDI & OBDII.

Cheers,

John

What are you hoping to log over the OBD port?

I've used similar things before and the update rate is soooo slow it's not normally very useful :(

I'm looking to use it to learn about tuning engines, namely my own. http://www.pocketlogger.com/ records some of the things I'm interested in RPM, Knock Sum and Timing Advance, but there doesn't appear to be a boost pressure sensor :-(
I just want to gauge what performance improvements puting in new spark plus, leads and stuff does.

I don't want to spend a fortune on it and http://www.aeswave.com/ CJ-II is too expensive at $369.

Cheers,

John

Hi.
x40 turbo cars don't have boost sensors.

They calculate what the boost is by taking readings from the Lambda sensor, the MAF sensor and the Intake temperature sensor.
