Any GS 400 owners try out Swift Racings New Race ECU for the GS4? How does it compare to the previous ECU supplied in the HFI/ECU package? Is it worth the extra bucks? Thanks in advance.

 

I placed an order last week and was told that it would ship in a week. My gut feeling is that I probably won't see before 7/4...

I will post a comparsion after I've installed it.

 

awesome.. i'm lookin forward

 

Henry,

How much is the upgrade? Is it a trade-in? I assume you send your's back to Mo when you receive the Race ECU.

 

I got mine installed last week and will post a writeup sometime week (or next weekend) on my impressions.

I'm waiting for my before/after dyno files from Mo for the writeup (in addition to some time constraints on my part this week).

Short answer - some perceptible difference, most noticable in the lower and mid-RPM bands. I would recommend/do it again for the $$.

QBranch - Marken has the details and prices posted in the Swift Racing forum on CL. I think it's $185 ($85 is refundable and for the ECU trade-in) plus shipping. The swap is basically an easy plug/unplug.

 

All questions regarding the Race Ecu swap should be answered in the thread below.
