Visit Preferences to set your user name Summary of change: '''Update''' $2005 Challenge: Car not going this year. A multituide of last minute problems has conspired to prevent the two planned cars from attending. * Odd problem #1 unless the serial port loaded or grounded the Fuel Pump wont run. * Odd problem #2 Bad ignition switch caused intermittent starting * Odd problem #3 Unknown coolant system after winter freeze -- ejected freeze plug * misc other stuff. Anyway plans are already underway for next year. And the cars/engines are partially built. ------ Physical Setups * '''Plans Turbo car ''' ** '''VEMS v3.1''' **2.0L ABA with a 20V AUG head ( variable valve timing) *** Stock KO3 from VW 1.8T *** Stock 1.8T fuel injectors 241cc/min and ~10-11ohms **60-2 crank trigger (VR) - aba **hall sensor on cam for #1 TDC ( very optional ) ** wasted spark setup with ABA coil ** or Coil on Plug from 1.8T ** LSU4 WBO2 sensor ** Nitrous activation ** Water injection -- maybe * '''Plans for NA car ''' ** '''VEMS v3.2''' ** 2.0L PL block with Port & polish 16v Head ** GSXR 750 ITBs ** Nitrous -- triggered this time ** move from v2.2 to v3.1 with proper PWM ** LSU4 WBO2 sensor ** Stock Distributor and Hall sender ** Bosch 008 module for coil. ** Drive ingition THRU distributor ---- VEMS needs/checklist '''STICKERS !

It should be a fully mappable ignition, by replacing the Typical Hall sender output from the Hall sender on the distributor to the Ignition controller. Ideas abound for a cheap and easy replacement. WaterInjectionController - This page will describe adding water injection to the racecar.. Please dont try this at home you can seriously damage your car. MembersPage/GrmRacer/GrmInjectorSetup -- what I have to do to get the car running.. Disclaimer: I'm trying all this stuff at once. None, some, or all of it may work to some degree or other. This '''STUFF''' is developed for off-road use, and the car only has to last about 5 drag runs and 2 autocrosses. So think about that before you do any of this. to the stock ignition box from the distributor or The 2.5 bar MAP sensor that you asked: MPX4250AP (MembersPage/MarcellGal) http://www.x-dsl.hu/genboard/ --------------------- ArmProcessorSubsitution Im working on the lpc2119 library for the possible ARM processor use.
