It may be the low boost you're running that is helping it not to detonate. just be carefull.. I don't want either of us being the first to blow a RENESIS that's turbo'd.

 

Jeff, great thread. Im green with envy on your turbo as well.

We've seen a video of Jon's (philodox) turbo...did you/or can you make a video clip?

I would love to hear yours for comparison.

 

Good work Jeff, and a nice read as well!

Cheers,
Hymee.

 

Jeff- the word on the street is http://www.eiptuning.com/ or there is a place in pa thats good, like 20 minutes north of the md/pa line, http://www.xoticmotorsports.com/

Hope either of those help.

 

Been to both. Much suckage.
I'll stick with Altered Atmospheres if those are my choices.
Jon is looking into booking dyno time up in Jersey in a few weeks. I'll go where he goes.

 

To address the E-Manage injector wiring scheme:

They wire the two primary injectors to channels 1 and 2, the secondaries to channels 3 and 4. The second primaries are attached to channels 5 and 6 as well as the sub channels A and B.

This is weird to me and I'm sure they have something going on in the maps to utilize this.

I have the secondaries wired to 1/2 and 3/4 (two channels each) and the second primaries to sub channels A and B. This gives me the ability to bump the secondaries and second primaries on seperate maps and leaves the first primaries alone since they are only useful for idle and cruise where the OEM PCM needs no help.

 

Very impressive work! Thank you for taking the time to document and share the data as you go. Also, the cool factor is off the scale.

Question: Where did you get the Kick @$$ Turbo set up?
Answer: I built it.

Very cool indeed.

 

Wouldn't this problem also have affected E-Manage operation when you were using it without the turbo?

jds

 

No, because I wasn't trying to add fuel so I didn't have the injectors wired.

 

Just a quick rave about the Profec E-01:

This thing rocks!

I have my LM-1 wired into it directly and now I can simultaneously read and log everything the E-Manage is doing and the A/F ratios. Now I don't need to keep my CanScan running to read the A/F.
It also makes a great boost gauge.

I usually have a window up with boost, A/F and injector duty cycle running, but I can pull up and map from the E-Manage on the fly and make changes based on my LM-1 lambda readings.

 

what do you mean by "on the fly"? you dont actually change things while driving, do you? that'd be like trying to read a book and drive...

 

Mazda Maniac
Do you know how Canzoomer wires up the greddy board in his unit?

 

He doesn't wire the injectors at all. You would have to do this yourself.

Uh, maybe I do, maybe I don't.:o

No, usually I pull over, look at the playback (I can watch what just happened with every single parameter over the last 3 hours if I like) and then dial in an adjustment.

 

ok thats what i hoped:D cool! you got a better pic of the the Profec screen?

 

nevermind

 

The protec is ~$600!?! yikes. Anyone seen it cheaper somewhere?

 

$600? Its only $495.

Considering it is a boost controller AND a replacement for my laptop while tuning, it is a pretty good deal.

 

oh hey jeff thanks for the offer to pick me up in Baltimore but unfortunately the wife said nix to the whole idea last night i guess ill have to wait until soemone out here gets one installed. looking forward to your reports (and philo's)

 

Jeff,

How hard was it to install the profec? I'm debating on getting one and if you don't mind, I could drive down to your place and maybe you could help me put it in?

 

Installing it was a cinch. It will be even easier on your car since the E-Manage is behind your glovebox instead of in the engine compartment like mine.

You will have to get that password for the E-Manage first to make use of its best functions.

Let me know when you want to wire it up. If you can't make it down, we could work it out when we hit the dyno in a few weeks.

 

OK. Dyno session is set.
Go to this thread for info:

Damn you guys are amazing!! Congrats...

Not to spoil the mood, or take any respect away from the hard work you've accomplished, but I have a few newbie skeptic questions...

If it was this easy for you to slap a turbo on, why didnt Mazda?

How safe is slapping a turbo on a car anyway? It seems you'd slap a turbo on any engine if you could!

Aren't there other factors to take into account other than just adding a turbo? How much of any increase in performance an FI device can provide would the Renesis handle? Fearing seal breakdown, blah blah, etc...

Yes, I'm jealous! But also skeptical. Judging by your sig, you are definitely the TURBO KING, and I bow to thee.

 

Mazda has to satisfy many gods, not just he power ones. Cost, Emissions, reliability, fuel mileage, all could be effected with a turbo. For sure, none of these kits are emissions compliant, which for automakers is prolly second only to cost in terms of priority.

 

Thanks.

A broad spectrum of reasons, almost all of which are ultimately financial.
Additional cost would either erode the profit margin or raise the price of the car out of its class.
Additional stress would bring more vehicles down inside the warranty.
Additional parts would bring in more warranty repairs.
Additional maintenance requirements would have led to user failures that aren't under warranty, provoking a ****-storm from pissed off owners who don't know they need to change their oil. Ever.
Insurance costs would rise as would fuel consumption.
A plethora of other considerations that I can't think of at the moment.

Yes, I would. And have. If it catalyzes hydrocarbons, I'll turbo it. I'm planning on putting a turbo on a go cart this summer for one of the neighborhood kids.

Yes. But one calculates the factors as a function of the normal operation of the motor. A properly designed turbo system simply makes a motor do what it already does but faster. This includes wear.
The trick is to make the accelerated wear the small side of the ratio.

More of a turbo jester, but thanks.

 

Thanks for the info!!
These may seem to be odd noob questions but please bear with me, I'm curious..

How much miles of life do you think this turbo has cut off your engine? Is this even possible to estimate?

Are turbos even practical for those who dont understand A/F ratios, boost pressures, etc etc.. it seems like its a lot of knowledge required for the average RX-8 owner wanting to go FI.

Thanks Turbo Jester!
