SCT xcal3 or 4? Advice needed

Featured Replies

#11

My xcal 4 is a 600 dollar paperweight. Honestly never use it. Have tried to use the live link software but can't seem to get it working properly and I only have a tiny selection of things I can read on the unit, no transmission temp for example which is what I was looking for. POS really I'd rather just not have it

  • Also to add to the above. We have ~6000 parameters mapped for the Falcons. SCT only have 3k and HPT 1.5k. We also support oddball varieties such as the BTR 4 speed FG Taxi, Ecolpi and the late model 2

  • Yeah I know. If I use the xcal4 on my BA then I can't even use my xcal2 and livelink to datalog.  The scramble was implemented to stop HP Tuners from reading tunes, however HP have now configured thei

I can still use the Android Torque app for logging certain info which is great, but Forscan has issues. :(

Might have to contact Forscan to get this sorted........

yeah forscan is very touchy. Paid for that app only for it to be useless and they kept blaming my phone and OBDII. Told them to shove it in the end. Use torque now

#14

yeah I got forscan on a laptop and no go.

Mazda, is your car tuned with an X4?  If so Forscan will never work.

 

Unfortunately SCT is still the better software to tune the Falcons with. So it's not really a paperweight!

Ah I thought hp was as good. Fair enough then. Sorry xcal :(


On that note then does anyone know can you read transmission temperature on the livelink program?

Wow did not know about any of that. I used a cheap eBay elm327 adapter with auto off etc and paid for torque pro and it was good but didn't seem to be reading things correctly like temps and boost etc.

Then I bought a scan tool obdlink MX and haven't looked back. It reads everything correctly and runs self checks and even gives me more info about the car itself. Always quick to connect and is accurate (as far as I can tell, confirmed by last dyno run). Using to keep an eye on timing and fuel trims and temps before I can get the car retuned.

Just FYI I may have found a golden goose but got a guy sending me an xcal4 at a very good price. Cheaper than an xcal3 I was about to pull the trigger on.

I'll keep you all posted.

As long as the logging device doesn't need to read the strategy to draw the Direct Memory Request info like Forscan or Livelink (Gen II with the x4 should be ok) then you should be fine.

ok so I have myself an xcal4 I got for $200 with 5 unlocks left it is married however.

 

I'm wondering if someone knows of a workshop locally that can do the $150 unlock (know a guy that did it in QLD) in Melb?

 

SCT have quoted me the same if I send it to them, and Herrod won't unlock them anymore apparently, they'll only swap them for a new one for $350.

 

I'd just rather not have to send it to the US unless I have to.

 

Thanks in advance again :P
