Krylon semi-flat black used on ash tray, shifter surround and cluster surround:

That's a brand new s4 radio surround and new center vent from Mazdatrix. You can see how close the paint match is with the painted ash tray. This is my n/a DD which is an s5, but I like the s4 radio surround better. It doesn't warp and bow like the rubber s5 surrounds do. Most often the s4 surround cracks are a result of people trying to remove them without knowing about the 2 hidden screws behind the center vent. D'oh!

of course, i really dont think it'll work as good as the stock coils without the blasters, blasters are made to work with an amp, we installed 3 coil packs and used 3 6AL msd boxes, and of course with the 6k rpm rev limiter chip to keep the motor in piece while break in, btw are you using a resister pack for your injectors? or does it get eliminated by a stand alone?

I know that the stock coils work better with an MSD box. But my question was, can you use the stock ignitor on after market coils.

The answer is NO!
last night I hooked up the MSD coils to the stock LEADING ignitor. Both spark plugs were firing, but they were weak. The stock leading coil ignitor is only designed to fire one coil so it's too weak for two MSD coils.

I stopped my experiment at that point, but you could potentially run the MSD coils with trailing ignitor because it is designed for two coils...


fd_dude, I'm using the motec, so no need for resistor pack. Good catch tho. I dont think anyone has asked about that.

Scip7, thanks for the pics. i'll have to check em out when i get home. Cant see'em at work

I haven't bought an MSD box yet, but am looking for a 6A if anyone wants to sell to me. I temporarily grabbed a used stock coil just to keep the car running solid.

A recent update:

Methanol installed. Just a stage one for now. sprays before the turbo, about 7" away from the blade. Now boosting 10 psi.

I had a fuel leak around the fuel filter. It was drving me crazy because it was a brand new filter, bought from MazdaTrix. I thought it was the lines or the clamps, but it turned out being the actual filter! It was a FRAM filter... so yet another bad review for FRAM.

I went and picked up a Beck&Arnley filter. Seems to be dry now, already noticing better gas milage.

I got a nice polyurethane dif mount, should have it installed pretty quickly. Try to get a pic update later today.

Not sure about everything else out there, but my MicroTech does.

WOW!!!! COLD AC ROCKS!!!!

I pressurized the system with r134a just to make sure it doesnt leak. i drove it to work today and it blew cold the whole way... ahhhhhhh

Once i am sure there are no leaks, I'll suck the system, replace the drier and fill with freeze12.

life is good

although, i did notice that idle went WAY down, and water temps jumped about 10*. i think I'll need to concentrate on doing some ducting around the radiator/condenser.

Update* I found a leak in the AC system. Sucked out all the refridgerant, and fixed the leak. I am now looking to put the freeze 12 in it, if I can ever find a place that will sell it to me!!

I've been concentrating on the Motec stuff lately. Basically, I've hooked up with Paul Yaw. He is a local Motec dealer and knows the software pretty well.

I will be purchasing the advanced tuning options soon so I can datalog and wideband tune.

YawPower offers dead band timing for fuel injectors. I am unsure of how this works with the software, but apperently, it will improve the drive-ability and response. So, he's got my injectors on his flow bench.

I am starting to get a good idea of how to tune this ECU, and also realize the MANY options that can be programmed into this thing. VERY exciting stuff.

The car is really fun to drive. Especially after driving this stock S5 around town. This S4 is really tight and responsive. Hopefully I can get some track/dyno time here soon.

Dead band is basically the time it takes for the injectors to "react" to the pulse sent by the ECU to fire. If the ECU knows how long this time is, it will compensate by sending the signal X amount of time earlier then it needs to be.

Allows for more precise injection. I've learnt more and more about Motec's because of this thread. And if I buy one one day - you'll be the bastard to blame for my 4K spending spree

LOL/\ hey classic, it aint THAT bad. I think you can get the unit, harness, sensors and advanced tuning for under 2500.

I think the dead band timing would make a huge difference in the response then.

I've learned quite a bit about this unit lately. There is a 'lambda was' table that lets you input where you'd like the lambda to be. Once you input what the lambda was, it will compensate for you. Then there is the lambda tuning. That is the option to make noise about. This is where you input your desired AFR, and the computer automatically does the rest. Once I get this figured out, I'll start on the closed loop tuning. Then this car will be dangerous!!!! (but safely dangerous)

The auxillaries are great as well. I'll probobly use on to control water/meth right off the bat. Paul was saying that I could use the other for a boost control *** in the cabin, and control boost on the fly!

We were having some issues with the lambda input coming from the AEM UEGO controller. We went through countless hours with a multimeter, and re-tracking wires; and all to no avail. The AEM gauge/controller output (in voltage) NEVER matched what the manual said it was supposed to be.

I got seriously pissed with this product, and tried using their Tech Support. They basically told me that I was wrong... So I sold the unit the next day, and traded it in for the Innovate LC-1 (thanks NMJ87T2). Unlike the AEM, I can actually program the output of the gauge to what ever voltage scale I want (AEM only gives you 5 modes).

I have yet to install the LC-1, but will hopefully have it in tonight. The tuning is coming along pretty nicely on the car, but without a proper lambda reading, I'll eventually need to go over some of the map again.

one of these days i hope to get yet another FC and have a build up like this

makes me drool

and also makes me jealous haha

HA, thanks.

Also, I sold the MSD coils. That route didn't seem like it was gonna work. I may still grab a 6A box in the near future. But most everyone on this board has advised me to stick with the stock coils.

Without that AFM, I can really hear the turbo spooling. It spools up pretty quick, but before I am even in positive pressure, that thing is buzzing under my hood.

I've already busted two K&N air filters because my filter is too low. I'm gonna put one more bend in that intake to get it up right in front of the radiator.

I'll try to get some pics of the diff mount that my buddy made. It's pretty tough looking. I'll need to get that installed soon.

Hopefully this weekend. I'll get that installed, get my O2 sensor bung moved back a couple feet, and get my car thro emissions.
