Innovate Motorsports SCG-1 Boost Control KIT, White, 52mm

Three hour install ( done the right way) Works excellent took some fooling around with spring pressure to get settings right eventually made 15 pounds of boost with a 7 pound spring. The ramping of the solenoid makes for an excellent boost curve, I had the blitz DSBC ID3 on my last car this is comparable although it had a completely different engine and turbo (twins) set up. The failsafes are great, plus you get a boost gauge, wideband O2 sensor and a boost controller, for in my opinion a bargain! ( In the pictures, the solenoid is mounted behind the passenger side strut tower, the map sensor is on the firewall next to the fuel pressure regulator, and the O2 sensor is mounted 20 inches behind the turbo on the downpipe)

This gauge is awesome. Wideband controller, boost gauge, and boost control all in one spot. I was very impressed with the cables. Everything has nice connectors and plenty of wiring to reach all areas. Haven't got the shift light to work yet, but everything else is top notch.

I have had my SCG-1 for about 10 months. For 8 months it worked flawless and worked as described. About a month ago I had started having issues with my wideband. It would jump all around on the AFRs and then it would finally just stick to full lean or full rich. Mostly would stick to full lean. Sometimes it would not even heat up and read the AFRs for a while. I would calibrate the sensor properly and it would last for a half a day, day or sometimes two days with no issues. Out of nowhere it would start doing the exact same thing again. Recalibrate and start back over again. It was maddening. I ordered a new innovate WB sensor, calibrated it and it was doing the exact same thing as the original sensor. Having chased my tail before on having a bad new part, I contacted Amazon and they sent me another brand new WB sensor to replace the already new sensor that I had just received. Recalibrated the second new sensor and it was still doing the same thing. That is where I was at with that problem.I had another ongoing issue that was very intermittent and I would overlook during issues with my wideband. The Innovate MAP sensor would just blink out here and there for just a second or two. When I made it to WB sensor #3 the MAP reading would stay on 29.8hg and blip to 0psi nonstop. SCG-1 is just occupying time and space in my dash at this point and just useless to me in every way.I looked online to see if anyone else has had the same issues and ways to test and diagnose the issues I was having. It was the same thing over and over, that they emailed tech support or they called tech support with no resolve. I also started noticing on a lot of forums that people were selling used SCG-1 units and started thinking that I have made a poor choice. That’s when I decided to call Innovate Motorsports technical support. I was on the phone with a tech support person named “Steve”. He insisted that my WB sensor was bad or that the o2 sensor location was burning up my sensors. Ugh, same problem with 2 new sensors and the original did fine for 8 months so how is that my issue here. Long story short, Steve decided to hang up on me instead of giving me any kind of troubleshooting guidance. I didn’t even get to explain my MAP issue I was happening before he hung up on me. Steve was a kinderchanic trying to tell a manchanic this, this dude needed some big fat crayons. I have contacted tech support several times through email and still have yet to get a response back.I’m not bitter, just disappointed all the way around with the product and support. This is my story and have learned my lesson. You can make your own decision but most of the folks that have put good reviews down on this were folks that really didn’t have the setup very long or perhaps they did get a good functioning unit to begin with. I would absolutely give it a 0 star if I could. Buyer beware.

While I am terribly happy with my investment, I just wish there was closed loop option so I don't have to keep fighting with the duty cycle and gain controls to get the boost number I want. However, it's an amazing product with many safeties built in to keep my motor safe!

Works great with no issues. I do recommend not using on a distribution block due to inaccurate readings.

Can't wait to get my trigger finger treated so I can install my turbo and the SCG-1 gauge ion my Polaris Slingshot.

Boost controller does great with holding low boost as well as adding 19psi over spring pressure.current settings:4psi springs in each (dual) 39mm wastgate94% duty cycle35%gaini see 23psiPros:-great safeties built in-easy to use-very accurate-can beat the price for a all in one gaugeCons:-the boost does not hit hard and is very linear for boost control. I would love a setting to allow the boost to spike then hold at pressure.-somewhat of a pain to keep doing pulls and adding duty cycle to get to your boost target.

really nice all in one gauge for a boosted car.. fit nicely into my swapped celica .
