about to splurge once again on intake and ECU. I have decided to go with the X51 intake but what's everyone running for their ECU?

 

I have X51 intake, fabspeed bypass pipes, fabspeed 200 cell high flow cats, EVOMS headers, and plenum so I now want the ECU

 

We use the EVOMSit software here.

 

I am not sure if the EVOMSit is there own technology. I know that they use to sell GIAC (which I had on my first 997 from them). I know a lot of people also run softronic www.softronic.us and APR is another www.goapr.com that I hear a lot of people talk about.

 

Absolutely it's done in-house by Todd@EVO. We took our Cayman S there, 3.8L GT3RS and 996TT 3.8 out there all for custom tuning on the dyno It's been great because we've gotten specific files for the hardware configurations we run (e.g. our exhausts or 3.8 kits).

 

That is great news, as I found the GIAC chip did nothing to help the NA engine in the 997 (only had a 91 Octaine flash). I know that Evo has a great name and I an sure that they are producing a good product.

 

We're happy that it's done in-house now in order to support their own hardware as well as ours

Here's an example of a GT3 with our exhaust (and NA engine) on 91:


Here's a lot with 93

 

Softronic,easy to do and great support

 

Nice numbers Alex. When you are doing the test, I notice that the time between the 91 and 93 octaine was nothing. Did you run 93 with a 91 program?

 

Correct using the IST within the ECU it adjusts to use a higher ignition map

 

What is the IST? Does it switch like the APR?

It's not like APR's which is user controlled through the stalk I believe? I've only seen that on their Turbo Audi set ups. Trick tho!

 

I ran Revo in one 997S I had and Softronic in the other. I would do Softronic again!

 

Hello,

I'm glad you have enjoyed the Softronic multi layer mapping or also known as adaptive software. We originally re-introduced it several years ago and many companies are moving in that direction. I can recall getting many questions on it and being told it couldn't work. Well Bosch started it almost 20 years ago and look at us now.


Best,
Scott

 

+1 for softronic. Scott is very knowledgeable and helpful. He has tons of experience with PCA and understands the programming. Easy/self install and noticeable improvement in throttle response and just feels like it pulls intake and exhaust upgrades together.
