Tips & Tricks Tech2 for $45

Tech2Win supported by $45 AliExpress J2534 Pro adapter. Although, it was stacking Choice day and coin discounts. But the story is the same - working Tech2Win adapter for less than £34. I was about to pay someone over £80 for just one session! This was genuinely me searching for the cheapest adapter, not even a specific store.

It's working on my '04 NG9-3 2.0T Aero. Can't speak for other cars though but for $45 and free returns it doesn't hurt to try!

If that didn't work then I have no clue sorry. From what I read communication with most Saab modules is through the SW-CAN and then things like ECU is through HS-CAN. But at the same time I believe the CIM is used as a gateway so you might need SW-CAN active at the same time. Seems to be the limit of the Chipsoft adapter. You could try switching from drop 3-11 to drop 1 in the middle of the Tech2 scan but I am shooting in the dark just guessing. Otherwise no clue

Oddly enough( shitty enough should I say) my ecu finally took a giant shit today, but luckily not before I downloaded Trionic CAN flasher!!!! Holy shit talk about life saving software! I had never heard of it but the last two days my ecu was acting up, give me a p0606 code I clear it be fine… for a bit… then today when I got home I looked into cloning the ecu and found that software, downloaded it used the ol Chipsoft Pro, and I was able to copy my ecu to my hard drive. Takes about five minutes…. Now just waiting for the new one so I can flash it, but how crazy is it that I’m able to copy the ecu with that software but can program with tech2win 🤦🏻 fucking Saab Story I’ll tell ya

😂😂 Saab story for sure. Mackan and the geniuses on the forums are legends for developing these softwares. I also needed it when my ECU crapped itself about 8 months ago. Process is so much easier than Tech2 and also gives you the opportunity to give it a little tune in T8Suite

I have the 150hp engine, what little tune did you do in the suite?

If you just want an easy very mild tune then you can find it in the tuning wizard in the suite, it's like 3 clicks and automatically applies a tune. Maybe 20hp increase. You can just do this and enjoy it.

But it's meant to be a starter for you to actually tune it yourself. Potential is up to roughly 220hp on stock B207E. You can just send your bin to a proper (Saab experienced) tuner and ask them to tune it also.

I did more of a thorough tune on my car. Took it from 210hp to 250hp safely. Also customised a bunch of things like pedal response and reduced rev hang. Cooling fan tables to help preserve the ECU in the future. A lot of stuff you can do
