Custom Performance Engineering's complete SPEED6 tuning solution

Just watch out for the time it takes to tune the MAF scaling. If you are running a different CAI than CP-E's then you are going to put alittle more time and money into your car.
If you live in the VB area I would help you. But it is alittle bit of a pain.


Yea, ive heard this as well. Thats why im going to go with the CPE CAI and sell off my MS CAI.

Why is it so much more difficult for those of us with a different CAI?
 
right on vinnie i wish i would have bought cpe cia, hey bro i appreciate any maps and help you could advise in tuning im new to this.. waiting for my stanback to arrive

You could always sell yours and get the CPE.. Thats what im doing. Someone will buy it bro.
 
And for your info.. the throttle plate issue is controlled via ECU just like the Fords...

If you can do a better job, by all means, man up and produce something. Otherwise, STFU and give respect where its do. CPE is doing a good job and i appreciate their efforts.

i was under the impression they still couldn't gain control of the throttle plate even with the ECM, cuz the plate would do a sort of 'flutter' or something at WOT.

and i wasn't dogging cpe's efforts, cuz they have made a great system. i was just saying i didn't like the price increases after months of them claiming to be hundreds of dollars cheaper than the xede. cuz now its going to be like the same price (rei)

Depends on how you want it. You can still probably order a beta like I have for like $630.

If you want the beauty of PNP, yeah you're gonna have to pay for it. Or drop your car off at my house, and I'll do it for the extra $200-300 cpe would charge you.(bump)
 
lol no doubt you will see flames, don't post anything even partially against cp-e (or anything that could be taken the wrong way, and turned around on you)...they are proud consumers/dreamers.

and thanks for the offer forest ;) haha, i'll probably end up getting the wire-in for real though..cuz its a nice price for a standback IMO. i just wanted to be able to unplug it...in fact i bet i could wire my own harness up!! wow thats a great idea..then i could unplug it whenever i wanted. cuz i'm not worried about warranty..since a mazda warranty doesn't mean sh*t most the time, and i'm nearly over the mileage anyways.
 
Sounds more like they just want you to buy theirs so they make more $ so they did it this way.

*waits for flames* (laugh)


Well, no flames from me! I just wanted to post a link that explains why we make our intakes the way we do:

We've had a lot of questions about our MAF housing design, so I discussed this issue with a member from another Mazda forum. The link I posted is in regards to the SPEED3, but most of the information still applies to the SPEED6. If you have any questions that aren't answered in this thread, feel free to PM me and I'll be happy to go into more detail.
 
thanks thats a good post..informative ;), i kinda wish it had numbers on the fujita too not just the MS intake. just cuz i'm curious what the fuel trim would be at idle compared to the numbers on a stock intake and your intake.

I've been preaching about what CAIs do anc can do to this car for just shy of a year now in regaurds to fuel trims.....but many call me crazy.

I've said that an improperly designed CAI would more likely throw off fuel trims before an upgraded turbo will......but I'm insane?

Just ranting, is the Speed6 inake equipped with the straightner like the 3?


-----EDIT-------
Here's a post I made about 5 months ago....I know I said it waaaay before that too! :)

NOTE:replace 'SIX' with '6' to see it. ;)

Thanks a lot (headbang)

Actually we'd like to see some numbers on the Fujita too! If we can get our hands on one we'll absolutely record some numbers.

If I remember correctly, I think the Fujita had a slightly smaller MAF housing as compared to the MS CAI. Since the inside diameter is arguably the most important factor when designing a MAF housing, this would imply to me that the resulting fuel trims may be slightly better than the MS CAI. But, bends before the sensor affect the reading, as do any weird transitions or protrusions before the sensor.

Forrest, I feel your pain brother. Even though that particular person in the thread you posted didn't get a fuel cut from his CAI, I still think you're right-on. I've been discussing this issue with customers (and even non-customers!) for months now, and I think people are finally starting to believe that we're not making this stuff up, lol.

Way back when, you could afford to skimp on the MAF housings because the ECU's weren't as sensitive as they are these days. I can't even begin to tell you how many calls we get that start out with, "I have brand "X" CAI and I have a fuel cut, what do you suggest that I do?"

In fact, I blame part of the problem on us. We try very hard to publish as much technical information about the SPEED6 as possible, but our website is sorely lacking. So when we go and rattle on about fuel trims, as we are here, we have no data to back up what we're saying! So, we have a host of updates in store for the site, many of which are articles that we've written about the many quirks that these cars exhibit. I wrote one article, not dissimilar to the thread that I linked above, and that will be up on our website shortly. We figure that people can argue opinion, but they can't argue hard data. So we're going to do a lot of testing to show people why we make our products the way we do. That way people won't have to rely just on our good word.

And to answer your question, no, the SPEED6 intake does not feature an airflow straightener. The airflow straightener does an excellent job at literally straighteneing out flow, which is really only necessary after a bend (from what we've found). Since the SPEED6 intake only has straight pipe before the sensor, it wasn't required. Our SPEED3 intake was our first intake that featured the MAF after a bend, and we weren't too thrilled about that when we started that project. I think our design was first to market, and we were really anxious to see what our competitors came up with considering the technical challenges. We were surprised to see that no one else chose to include an airflow straightener. Well, Cobb has, but their intake isn't out quite yet.

no...they aren't going to do that(yupnope)
 
Any updates on them connectors, Knowing my luck the ship was sunk during the shipping process so now I'm going to sink myself :) j/k <3 cp-e
