i don't get why people ahve such difficulty with the ABC alone. I run 19psi solid on 1 map and 21 taper to 20 solid on 2 of my maps... and i'm not using a MAP sensor and i'm a noob to tuning.

 

I only began finding the ABC to be troublesome when I needed to run higher than 22psi of boost, and be able to maintain it better through redline.. The aftermarket turbo guys have a few more issues simply because of their wastegate function, and whatnot, the ABC/Stock solenoid works well, but doesn't offer you the range of adjustment you'd have if you used the Perrin or GM solenoid mod..

 

Hey, any word on UTEC + Perrin EBCS? I'd appreciate the update. Thanks.

 

so running anything beyond 22 psi or having a turbo upgrade, you would recommend a 3rd party boost controller or an upgraded solenoid? how difficult is changing and then calibrating the solenoid, or does it work on its own once all the connections are hooked up?

 

Yeah, it actually turned out to be a real easy mod.. I should really post a how-to, but I was hoping I'd find the correct connector to make a plug and play wiring harness for the solenoid before I did that.. ITs really under an hour of effort.. the boost control aspect, its hooked up exactly like an MBC, so you know it works like an MBC, and the boost maps have to be redone if your using open loop boost, but it took me 5-10 minutes to find where it wants to be (around 60% duty to get 20psi approx) in closed loop boost, the numbers were roughly the same, 350-450 range in the cells to get 22psi.. The solenoid gets hot, so it needs a resistor, I just figured out which is the correct one to keep it from getting too hot, but I still need to test it for a few days...

 

The Utec uses a duty cycle to control boost. All you need to do it wire teh EBCS into the wires for the stock BCS. Then you can tune the EBCS using the UTEC by going from 0-100% duty cycle. Very simple it will work on ANYTHING that can control the duty cycle.

Now that is out of the way. Some of the Suby guys have used them some love it some hate it. I don't think I would buy it when you can get the GM one for way cheap.

If you have any more questions you may want to make your own thread to keep this one on topic

Hey Malibu can you pm or post that resistor info after I test for boost leaks I want to do a complete retune and would like to be running closed loop boost control.

BTW CBRD I had a buddy trying to tune on the UTEC with a GT35R and he said it was to hard he would go from load site 10 to 50 to 100 skipping the load points in between and he said sometimes he would go from 100 to 20 or so. It was very hard to tune.

He finally ditch the UTEC and went with the AEM and has had zero problems tuning it.

I think the UTEC is a great tool. But it should be ment for people with a stock turbo or a stock size inlet turbo. The UTEC sometimes goes crazy on a 4" inlet.

okay, I'll have to post this in an official how-to, but the resistor should be a 1 watt, 10 ohm.. that should be enough to cut down the current to keep it from getting too hot when its over 90% duty..

 

Oh, and about the big turbos jumping load sites, That is when you end up needing to use an alternative type MAF or using a MAP Sensor for the tuning.. It becomes much more predictable...

 

I will be putting it in tonight and I will let you know.

 

I will do a full write up after more testing. So far It has improved but no eliminated tappering. On my methanol MAP it will allow me to run 26 PSI tappering to about 23 at Redline. Which is better than falling off to 19 like my stock solenoid did. Also it totally eliminates boost spikes in 4th and 5th which is very nice.
