Hey guys Im trying to come up with a solution to log boost on multiple cars with an external device, technically for evos I can just buy an extra omni 4 bar and just take to car to car so I can log and plot boost with everything else, however for multiple types of cars for example SR20 nissans, the only thing I can relay off of is the boost gauge or "MAF G'S/LOAD" which doesn't really give you an exact number since they are not speed density based. Ive looked into the Zeotronix stuff and it seems like a viable option I just dont really care for the software. Another possibility I was thinking was possibly an AEM BOOST WIDEBAND FAIL SAFE gauge and just wire that into a CIG lighter for portability. Considering that software is pretty decent but I havent been overly impressed by the accuracy of the UEGO. Any other suggestions you guys can think of? And as I said this would be a car to car solution.

 

Bump on this also

 

Do you know Protune products? It's a brazilian company.

Their data loggers can connect to OBDII and have two analog inputs that could be used to log AFR and Boost. There is also an expansion module that will give you 6 more analog inputs and 4 more digital inputs. It has a nice LCD screen ranging from 3.2" to 5.6". The data analysis software looks good as well.

The price is not exactly low, the less expensive model costs R$ 2099, which is around USD 560 in today's exchange rate.

Google for Pro Tune TDL 3.2

PS: I don't have any kind of relation with this company, but it is widely used here.
