Re: Were Should I Spend my EG33 Dollars to Kick Ass.
Hi Mike,
I run MS and had ignition issues initially...there's a thread on the MS forums about it and references the fix we found. I'm happy to give you my files if that helps? Matt |

Matt, do you know where along the wire the resistor was added? Also, a question. On the MS forums one of the fixes for sync loss is adding resistors, but sometimes they are added inline with the signal wire, and sometimes, they are added across the signal and ground wires. Or sometimes both. What does this accomplish and why would that be a remedy? Harvey? Or anyone?

Re: Were Should I Spend my EG33 Dollars to Kick Ass.
I don't know how you guys can put 2-3K+ worth of parts in your engines, take months and even years to build it all up patiently, nicely with a lot of love and then run it with something so unreliable, troublesome and nasty. Don't you think it would be better to spend that coin on the ecu and run the stock internals or at least reduce internal work etc?
The ECU is the most important part in your car, my advice is to invest in it (doesn't have to be expensive, just run something known to work without drama) or you will pay the price via by wasted time, poor dyno results or higher costs for a tuner trying to figure it out / fix the signal issues. |

Basically, it's only such a pain in the ass the first time around, then it will be easy for the next guy to get his setup. I am just unlucky not to be that second guy. Mike too. And then once figured out, we can be saving, what? almost a grand compared to a hydra? That's a solid amount of money that could go to parts or whatever.

At that price there are other options - you can buy a 2nd hand Microtech on ebay for a 6 cylinder for $400 odd bucks. You can then send it to Microtech and have them set it up for the EG33 which costs about $150 and then a handset to tune it for $200. So you could be setup for $750 odd and the ecu is FAR superior to the MS. The microtech ecu actually holds the world record for the quickest EG33 / Subaru / WRX on the planet still to this day. Or you trawl the forums until you find a 2nd hand Linkplus G3 or Vipec come up for sale etc. There are a lot of other better options, we just gotta be smart about it. |

If the signal is reduced by a mismatch of the impedance, the voltage will be lower, and the zero crossing point will not be as sharp, and harder to detect. The problems stem back to the Inductive pick-up that the engine has. These are an electrical generator, that produces a voltage wave form that depends on the circuit load, and the rate of change, rpm. This allows the signal to be too much voltage, from the speed or a higher than normal impedance, or too low a voltage from too low a impedance. Also because they generate a such a low voltage, it is prone to interference from all the other electrical equipment. To be reliable they need the input circuitry to be matched to the inductor. If the impedance is too low, fitting a resistor in series with the signal will prevent the voltage from being reduced. If the impedance or the voltage is too high, fitting resistor across the signal or the pot as a voltage divider, will reduce the level, It would be better to replace the inductive unit with a Hall Effect unit. These produce a 5v square wave that is immune to interference, and does not change with speed or load. A shutter could be fitted behind the crank pulley. Harvey.

I agree. Went back and checked my notes. What was recommended to me was 1.75" into 2.5" with 25-26" long primaries. I think the builder talked me into 2" into 2.5 to better match the opening of the elbow exh after porting. Hope I don't regret that. Thanks for the imput. Mike |

Re: Were Should I Spend my EG33 Dollars to Kick Ass.
Very interested in the cam upgrade... if that means ecu and map and injectors I guess those too... I want a little more kick in the pants very nice thread I will be watching diligently thanks for all the hard work guys!
