New Mafless Uni 830 Tune It's Alive!!! 1st crank and a beautiful idle! Long...
I decided that Unitronics caters to individuals like myself, so I went with their 830cc tune to allow room for growth ...
Most of you know that I dumped my GIAC / TorqueFactory tune a while ago because I wasn't going to buy four more Injectors that are very loud and have a pencil spray pattern, the new 830s are so quiet it's so nice. My wife came out and said "Your car is quieter, it doesn't sound like the head is about to break"
Saga:
I elected to get rid of all items that have caused me trouble in the past and keep it very simple: No MAF, No Evap, No SAI, No N112, No ESP, No N79(I went with a Greddy ProFecBSpecII). Saved 25.5Lbs, and there are still a few items in the fender that I haven't gotten to yet.
I had issues with the powersteering line so I added a power steering cooler and rerouted the lines.
I also didn't like the box that holds the J299 and J271, so I relo'd them while I was at it.
All the "deleted" items left me with a lot of wiring harness that I didn't need I unwrapped and rewrapped pulling about six foot of harness up into the space under the windshield keeping the engine bay clean.
I had a donor harness for the passenger side of the ecu as I needed a factory wideband connection. If I had it to do over I would not have bought this harness (could have saved $100). Instead I would have added the pin to the ecu and changed the connector for the O2). I was pretty familiar with adding pins, since I had to add a pin to the drivers side to support my 15Ohm 25watt resistor to make up for lack of VVT(VCT)
Final Note the "donor" ecu was from a VW, I belive that was sporting 4motion, I noticed on the ecu label is said Motronic 7.5, I thought we ran 7.0, anyway my haldex doesn't work now. No biggie, we'll get a different donor ecu and get it all worked out. The only code I have is "18058 - Powertrain Data Bus: Missing Message from Instrument Cluster
P1650 - 35-00 - - "
Injector comparison, so much quieter and the car idles so smooth now!

Hard lines and power steering line aren't in the way anymore!

I'll do away with the MAF Holder in the future, the catch can is under the MAF. The Greddy Soloenid is behind the wire race way.
