DEJON-Mitsu 16g Turbo Install

Should also be either part of the kit or an option to add-on on the same page (I know you can seperately but still). Price hurts, but is about what I expected, you get a LOT of parts for $1800! Are you going to offer an intro price or GP for the kits? Coming home from iraq in 2 months, could make it a birthday/homecoming present to myself

I don't want the page to get too big with options, some people will only want what they need, others will want all pipes. I can work out individual packages to people who already have our IC pipes, want all or any combo. Once a combo gets popular, we'll add it.

AS for the IAT2-reg, yes you will need it, along with a MAP-Saver if you use the Cat, Manual boost controller, and probably an independent boost gage for which you may want an A-pillar pod. Again there are so many combinations, I can't pre-guess what will be the most popular, just list what you need and let you select.

As for discounts, my practice is to offer products at the lowest price we can make money at and not discount for every club, event, group, and person who wants to build a pseudo-race car. So we offer only package discounts and sometimes event discounts. So our prices are meaningful, not artifically high to be bargained down.

Is the Map saver diff then the IAT2 reg? Didnt see the map saver listed on your solstice page(s). Why do you only need it when there's a cat, the extra backpressure create a few too many pounds of boost? I had planned on going catless, and trying 25psi to start, tuned several cars before.

may be a little off topic, but the downstream O2 is a standard narrowband sensor correct? should be able to put an O2 sim in it if your running catless to get rid of the code. that would get around upstate NY emissions at least.

A little history - there were a bunch of us that installed the first Solo high flow cat. They set codes immediately. I tired the electronic sims and the mechanical extensions. Nothing worked for quite a while. Solo finally found a fix, it was merely moving the O2 position about a 1-1/2" further to the rear and rotated about 45 degrees. You also had to use one of the O2 extensions. It had something to do with the fact that the sensor was out of the flow in the original position. I can tell you this, when the sensor was in the wrong position it did not have enough of a delta for the ecu.

Dave:
wouldn't it be worth a try to use the Solo cat?

Do you still need the iat2 regulator when you're running under 20psi? I mean the 16g will work just fine at 18psi.

The MAP-SAVR is GONE! I must have made a mistake when I updated the web page, I'll correct it tonight

Solo is going to make me a cat downpipe with their better cat.

The problem is not a Cat error code but a P106 which is a MAP sensor error code.
If you run catless, you should be OK without the MAP-SAVER.
DO you need it with the stock turbo and stock downpipe while running 22+psi with just the IAT2-reg and an MBC for boost control? Jack, do you have the setup to test this out? If you need an MBC, pm me.

That's Correct

Dave:

Question: How would the cat affect the map sensor, if anything, the cat would reduce boost a little, therefore, reduce the possibility of the map showing over-boost??

Answer: I have the mbc installed and I am slowly turning the boost up. I am now running at a flat 22 psi. The problem has been the cold tires. At 22 psi I am getting excessive wheel spin in 3rd, 2nd gear is not even usable. It is supposed to be dry/warmer this weekend, that should bring some good logs. Currently, I'm at 22 psi without any ecu issue, but, have not been able to take it all the way to redline in third. In the latest logs the boost looks like a flat line with little if any deviation or depreciation of boost.

I have the IAT2-reg, but, will not install it till I get to the boost level where the ecu starts complaining. The nice thing about both devices is that they go on/off in minutes. I also have some high-res install pics, that I will send you.

I'm going download a log from yesterday, I'll convert the maf reading into hp and will let you know what kind of hp the car is making with your intercooler and mbc at 22 psi.

"Question: How would the cat affect the map sensor, if anything, the cat would reduce boost a little, therefore, reduce the possibility of the map showing over-boost??"

I'm just guessing here but maybe the ECU considers the engine not completerly "warmed up" without the Cat and doesn't react the same way. I know it seems strange, but I did about 20 runs without the Cat and never got an error code, then 4 runs with the Cat and got error codes every time.

lemme hit ya with this one- the cat provides enough backpressure to reduce flow a small bit.
That reduction in flow places it in a area of the comrpessor map that can produce more PSI before choke.

Whatcha think? flawed logic?

I don't know what to think. I need more correlation data. The weather here has been too bad to test WOT further.

I'm working thru some driveability improvements with the 16g kit which don't require dry warm roads for traction. The boost comes on so fast that it makes part throttle driving more difficult. The problem seems aggrivated by the electronic throttle that is set for the stock setup where the ECU drops boost to 14-16 from 3500-5k and doesn't give 1:1 input to output around 1/2 throttle. I've made improvements by tightening the BOV and other tricks. Sure hope HP Tuners gives us throttle map tables to play with.

[kwtoxman]

Do these have an open loop vs closed loop FI operation like earlier FI with warm up vs normal operating temp?

kw.....

[BaldTurboFreak]

To my knowlege, no It's all closed loop the instant the sensor is warm.

It takes about 30 seconds and it is in closed loop.
