i have a question about running an MBC in conjunction with the Upsolute ECU. will boosting 1-2psi over what the car will be boosting with the Upsolute software trip the check engine light?

im planning on chipping my ecu next week and havin an MBC installed as well to boost just a little bit more, but i dont want a CEL on because of it.

The danger with this type of tune is that the heat inside the engine increase quite alot.. the harder you push your engine, and more heat above the pistons you have... and chanses for the pistons to melt is 50 % bigger. We have had 2 members with a complete engine melt-down, if u are gonna use this.. please install a turbo gauge so you have control. otherwise its gonna be expensive! Trust me..

you dont need to boost more with an upsolute if your running the stock 12T turbo. it just runs out of steam and is inefficient. unless you have intercooler, downpipe, exhaust, and air filter i wouldnt boost over 12-15 psi

How about Water Injection. I don't wanna sound like an aquamist commercial, but if you guys run a lot of boost an heat is the first danger, cool it!

'm not suer it will work with the boost control. True its the heat that is the first danger but its because the wastegate wont let go with the pressure from the turbo...

Aquamist test results:Lowers cylinder temps by as much as 300 degree Fahrenheit = 148.8888889 degree Celsius. If it cools cylinder temps it's a step in the right direction. The unit is programmable(by boost levels) so you can optimize when you want water injection to kick in. Will work with a boost controller.

Don't know why it wouldn't work.

The 1S aquamist is triggered by an adjustable pressure switch.

If you run 1.5 bar of boost you can set the switch to activate at 1.1 or 1.2 bar.

I use aquamist and a boost controller (not at 1.5 bar though,....yet Smile )

Ok, then I surrender... Will not argue about something i'm not 100 % positive sure! Ok then it will work with water injection.... Very HappyVery HappyVery Happy

Sounds like you are going to put your newfound knowledge to good use.

No not right now, I have tons of payments to do first. But I sure like the idea of it

How well does that aquamist or whatever work? Are the gains worht it, I mean, obviously they help some since you have it installed, but what are the gains... Razz

Compared to an upsolute chip, in terms of HP/dollar it's too expensive.

Just installing WI won't gain much. If you add a lot of Methanol it might. The gain is that you're able to increase boost pressure further than without WI. The knock-limit is raised because of the water, timing can be adjusted.

I mainly have it for peace of mind. Future tuning would/could really benefit from WI.

Check out the WI forum, lot's of people adjusting air/fuel ratios, inceasing boost and gaining a lot of power. But just adding the WI add's some power, but not much.

Still, I love it! (despite the reservoir problems I had).

Those 1.5bar people, they NEED it.
