Summary of change:
'''Non VEMS Related Problems and Upgrades''' These items are not directly related to installing VEMS, but it's worth documenting them for completeness. And they may be useful to someone at some time... '''Fuse board''' VEMS adds about 5 new fuses, and possibly adds or removes a relay or two (depending on your car). Instead of just having these extra bits kicking around loose, I thought I'd put in another small fuseboard. This quickly became an excercise in rewiring the whole car, since a few wiring gremlins had been discovered. A useful modular fuseboard was acquired from A company called "Vehicle Wiring Products". It is considerably smaller than the old one so will allow me to gain an extra couple of inches of legroom in the passenger side. The engine, cooling fans and headlamps have been put on to the new fuseboard, along with the main ignition relay now. The rest of the wiring is taking a lot of time to figure out!! [Fuseboard wiring pic] '''Fuel Pressure Regulator''' See the section headed "1st Long Tuning Run - 05/02/06" in MembersPage/DavidBlades/FuelTest The fuel regulator had died shut and replacement seems inevitable. I've always tried to see such things as oppertunities for upgrades, so I have found an adjustable regulator. The standard TVR reg was set to 2.5 bar. This simply isn't enough for good atomisation, so the new one should have 2 benefits - apparently bigger injectors and a better burn. Picture of modified injector rail and new pressure reg. Note the addition of a pressure gauge for easy testing in the future. http://www.aqyz05.dsl.pipex.com/tvr/assembled_fuelrail_sml.jpg All back on the car now. It's certainly cleaner, but it's a bit obvious that the car's modified now. [Pic of new adjustable FPR] The snag is that the fuel pump sounds a bit strained being asked to pressurise the rail to 3.5 bar. Oh well, maybe that Bosch 044 pump is in order... '''Exhaust Upgrade''' I think the "1st Long Tuning Run" incident has also killed the cats. New performance manifolds are being sought to fix this. Built to my specs with proper wideband and EGT ports fitted straight from the factory. Exhaust leak is obvious here. Some connectors also got melted, but they aren't visible here. [Leak] Is this cat dead? [Exploded cat?] Back to MembersPage/DavidBlades
