CAN BUS and logging?

Possible... @rabtech may have done this a time or two...

I think as long as you aren't running stock ecu and have an OBD port you should be good to go

The short answer is no. There is no OBD2 interface for the stock ECU. Even if you wire a OBD2 port up to the diag port wires it doesn't output data that can be viewed.

This will not work for what your wanting to do BUT if you just want to see the data you can buy the reading software from Bob at MEFI and use a PC to see the data. Dont let this confuse you.... It is only going to show up in his software and cant be ported to another program.

it's a little over my head but here you go: can bus and logging.

Lets put it another way... Only 1 or 2 people to companies have ever been able to offer a product to read the data from the Slingshot CANBUS.

I have purchased RZR diag readers in the past and they will pull some data HOWEVER they will set Check Engine lights on your dash and they will only tell you one or two parameters. Polaris has really done a great job in tweaking how the data is being sent across the CANBUS.

I gave up and switched to A Haltech ECU. I now have true OBD2 plug with all my data at my fingertips. Wish I had a better answer for ya.

You are mixing the terms Canbus and OBD2.

Obd2 is a comm protocol for externally accessing the ecu and Canbus components.(aka laptop connecting to vehicule).

Canbus is a comm protocol between different modules in a vehicule (aka ecu to stability control module to abs module etc). Its not used to connect to a laptop.

The OBD2 port on the SS is not standard therefore it won't talk to OBd2 readers out there that are not wired and programmed for the Sling. Mefiburn has a software and plug for the SS that works, and will log to a laptop for a while.

The Haltech ECU can communicate with the other modules in the Sling over canbus, so it will work with stability control and throttle control unit (which is not in the ecu itself, its in the power steering unit) and also ABS will work.

Other functions managed by the ECU like cruise control doesn't work for now, and if you switch to a canbus dash, fuel level, warning lights (check engine, high beams light etc) and flasher lights (in the dash, outside flashers will work) won't work unless you wire something to make it work.

You can keep the stock dash and work with the Haltech Ecu, in which case you would only loose cruise control.

The haltech 1500 has some limited logging capabilities by itslelf, but can be connected to a laptop while running and you get unlimited logging.

It sounds like you give up alot going with a Haltech ECU, unless you also get the dash as well.

Actually, no, you only give the cruise control if you keep the stock dash.

With the IQ3 dash you loose a lot more lights and stuff, but you gain displays for everything the ecu is doing, so you can display oil pressure / temp, water temp, boost, AFR, rpm etc all in one place, something that would take you mutliple external gauges to monitor.

You can also have much better problem detection and engine saving measures put in place with the Haltech, for example if fuel pressure isn't right, you could have the ecu lower your boost to avoid blowing up the engine.

You could have the engine shut down in the case of an oil pressure drop, and the list goes on. These are things the stock ecu cannot do.

wow sounds impressive.
I guess the money I just spent on a gauge pack could have gone to haltech

What about tuning?

Tuning is done thru a local shop, though maybe now some guys may have a tune for a stock engine that might work well if you don't have many mods.
