Re: what exhaust are you running?

I will also vouch for the BRM exhaust. I was running a 2.5" with no resonator and dual tip magnaflow muffler and I loved it. Sold the car - now running no-name pieced together exhaust in the s12. The ONE complaint I had with BRM was the welds rusting. They used stainless tubing and mufflers, bu...

Re: Nismotronicsa

Sure thing, the only difference is I'm running a "Motorola" 2.5bar MAP. I put "Motorola" in quotes, because if you get a "Motorola" 2.5bar MAP, you are really getting a Freescale Semiconductors MPX4250AP (or board mounted equivalent). The map sensor I am running is the ...

Re: Fuel Pressure Regulators

That's mostly correct, however you will probably see fuel pressures closer to 60 PSI, so make sure the FPR can handle that. At atmospheric pressure (0 psi) the fuel pressure should be about 43. With a 1:1 rise in pressure, at 15 psi boost, you are at 58 PSI of fuel pressure. But yea, that is all cor...

Re: Another dumb catch can??

There's not really a good way to avoid plugging those holes. The reason you don't want to run your PCV there like stock is that any time you are in boost, those are under positive pressure, meaning your crankcase is under pressure as well. The PCV system is designed to work the other way - the crank...

Re: Oil Line comfirmation please?

Re: Another dumb catch can??

You will want to run the catch can to a vacuum source - AKA pre turbo. Some people just vent the catch can to atmo. You're sure to get many different opinions. What I will say is your method currently will not work.

Re: Nismotronicsa

So both are 10 bit....so, maybe I'm incorrect here (I'm a mechanical and not an electrical engineer) but it would actually be better to use the O2 input sensor than the ADC. Here's the logic - using the O2 sensor and a divide by half voltage divider (or programming the WB02 to output between 0-2.5V)...

Good point on the programmable output, hadn't thought about that. That's defiantly the route I am going to take.


Now to figure out the ECU model issue. Maybe tomorrow I'll take a look at the FSM and see if there's any info on models that used the EGR temp sensor.

Re: Nismotronicsa

For the iat you only use a resistor inline, no voltage divider. Check the nismotronic manual, it has a diagram and what resistor to use. That is how I have mine setup in my daily. I am running a CA emissions ecu but I couldn't get the iat to work through the ecu itself with a gm sensor, only with t...

I had a similar issue that ended up being a kink in the harness near the injectors where the inner wire had poked through to the shielding, effectively shorting it out. Fixed that and it fixed the code 34.

That is correct, if you want to run it with stock ecu and not tuning, you will have to run the stock MAF. It won't run as well as it could, but it will run fine with stock injectors, maf, and ECU.
