[QUOTE=coxxoc]What makes the s5 harness better than the s4 other than it being a couple years newer?
And, if you hate the old harness, how hard is it to make a NEW one? Just measure the old lengths.[QUOTE]
The S4 has horrible cold solder points and grounding problems from the factory, whereas the S5 is better. Not sure to what extent, but it is better. If I had an S5. I would probably just save up for a JDM pimpdaddy powerfc for s5 fc.
Have you looked at the stock harness? It's very thick and lots of stuff. I would not want to recreate that thing at all. It's entirely possible, but would be a huge PITA
The rtek 2.0 runs the ORIGINAL map from your turbo ii's computer, all you are doing is modifying it by a % plus or minus the original figure. When you reset the rtek to 0, its the stock map.

Cold solder joints on the printed boards exist just as readily on S5's as they do on S4's.
If anything, the S5's were a little worse.
I don't really understand how you can say the stock harness is so bad. What vehicles of the same time period are you comparing it to? Testing MANY stock harnesses, both N/A and TII, S4 and S5, they have all come up fine on both a Megger and Ohmeter/diode test.
I have never seen a wiring harness failure that was not caused by owner error.
The most common electrical problems are caused by cyclic heat failure of the plastic connectors and by poor grouding connections, both are far more easily repaired that building a new harness.
Now, then, let's ask ourselves how many aftermarket EMS's have had failures due to aftermarket wiring harnesses.
I can count several just by myself.
Sure, its possible to build a great aftermarket harness, but are you more capable of doing that than Mazda's electrical engineers and assembly line?
Based on your responses, I doubt it.
Please tell me exactly why the stock harness is so poorly built. I'd like to know which wires you megged out, what the results were, and to what gauge you would change them to, which wires you would add shielding to, what spec wire you would use to in building a new harness, etc.
Otherwise, you're just being ignorant.

it runs strait out of the box with the stock tII ECU map??!! thats great!! i was just scared of the timing.. i never really tuned my car except with my SAFCII..
im liking this thing more and more everyday!!

The reason why the stock harness sucks is because of it's age. I bet back in the first few years it was perfect.
After 15+ years they have now gotten a lot of heat cycling and other conditions(water/etc..)
Most grounds are very bad and some wires are very brittle.
If someone made a new replacement harness I would buy it. If I could source the same plugs then I'd just make one myself.

why argue about s4 or s5 harness differances when the rtek is only for the s4:-( Is there any thing similar for use s5 guys. They sayed an rtek chip for the s5 was in the working for years now.

oaky time for me to chime in and ask some questions. I have a street ported s4 t2 engine with 550cc injectors all around.( I plan on moving to 720 cc in the future. My mods are
Street ported intkae and opended up primanry. and SP secondarys. Intake and opne DP till I have acahs for fulle exhuiast . I also have a crazy big ported wastegate. I plan on running 9psi on my stock turno. Well what retek would be best for me ras of right now? I havea f-conn too .

You can use the 1.5 version which has some of the features from the 1.7, then upgrade to the 1.7 later, since a % of the money you spend on the 1.5 is credited to the 1.7, and a percentage of the 1.7 credited to the 2.0.

just my 2 cents....
the stock wiring in our cars is horrible. it's the most poor quality wire I've ever delt with. I'm currently finishing up biulding my own custom harness to use with my megasquirt, because my car would barely even run anymore due to stock harness issues. plus it gives you a chance to get rid of all the wires that you don't need anymore because they go to stuff you've removed.
it's probably because of a lot of reasons, one of which is the added heat rx-7s put out, and how old our cars are, but I still think it was just bad quality to begin with.
but the rtek 2.0 looks nice
it looks like a really nice, low budget, safe way to not blow up your car. which is always good

If you do MS you have to modify/replace some of your sensors to work right. Also the tuning interface for the rtek can be bought for 30 bucks or so (ANY old palm) and can be tuned in the car w/ aux input for wideband. MS you'd have to buy a laptop to tune and there will be NO presets to work off of. You do it 100% on your own.
For a guy doing it yourself w/o access to a dyno to tune w/, get RTEK 2. Get MS if you want the novelty of building (and finding all of the parts to build) yourself. Both will be capable of a good amount of tuning.

You also can get prebuilt megasquirts (for a little less), and there's enough people running now that you can get a decenet basemap to start, so it's not starting from scratch.

EDIT: Also, the RTEK7 has 3 different injector presets, thus, I don't have to look for a 550/720 basemap for my MS.

The 2.0's install and setup are extremely simple...just 3 plugs, and the car runs. Also, no one needs a dyno to dial in anything, just a wideband.
