apologies for this being a bit of a cut and paste update
more playing with the omex today, it already had sensor calibrations on it when i picked it up so those were used for ease when we first connected it up, checked them out today and the ecu was reading 40 degrees when the car was 90! re-calibrated the sensor values for all sensors after this.
also had a bit more of a play with the map and ran out of injectors! lol
scoured round the parts store, *read - garage full of 'bits of metal' as girlfriend calls them!* found some of my brother's old rover injectors, checked the part numbers and found them to be around 1 1/2 times the flow rate of my beiges. these are being fitted tomorrow and we'll see how she goes
more fun today! fitted said rover injectors and re-set flow rate in ecu and changed map to suit, with me driving and my mate Graeme in the passenger seat watching the LM-1 wideband lambda reader and laptop on-knee adjusting the fuel and spark tables. got it fuelling right at 16psi, which is where it peaks at the moment. so we are back dealing with 4th gear wheelspin, always fun.
wired the now redundant ABS light to become a shift light at 6000rpm which is quite cool and went down the motorway at 60/70/80 mph respectively and set the fuelling to 14.7:1, so i can have maximum fuel economy when on longer journeys.
had more playing with the omex over the last few days. fired the car up to go to work and it ran rough? odd, so i turned on the lm-1 reader and found the car to be running lean. popped the bonnet and had a look at the pressure gauge on my FSE valve, (an increbibly handy addition) and found the fuel pressure to have dropped off. popped the rubber bung out from the top of the tank and un-clipped the pump plug, found the pump wiring to have melted severely in the plug on both the wiring loom and on the tank as well.
jacked the car up and dropped the fuel tank out to take a look.
As this has been a repeat problem with this car i needed to find a soloution as over the last year it has melted the fuel pump relay (replaced with two higher flow relays ), melted the plug on the loom twice and now the top of the tank.
with the tank out i removed the pump and then drilled through the top of the pump/tank insert. i then ran two large gauge wires straight through the hole, with grommet, to the pump. used a petrol-resistant sealant to seal around the wires and then ran the wires through the main body grommet above the tank and straight to the pump relays. re-fitted the tank and primed the system, more pressure than before, great! turned the pressure down on the FSE and checked running again. perfect!
just attempting to sort the battery and air temp compensation tables now
please note that on the Si i intend having an in-tank pump feeding a swirl pot with two external 044 pumps to supply to the rail
went, don't kill me, to ultimate street car @ santa pod this weekend. Travelled down this friday @ 6.30am and used 3/4 tank to get there, around 200-220 miles.
went with my mate graeme in his fiesta, Andrew in his golf mk2 VR6, James in his golf tdi and Gina in her fiesta style
ran the car on this strip,
graeme without nitrous ran 15.05 @ 92.14mph
graeme with nitrous 75bhp jets ran 14.477@ 94mph
i ran a
[email protected] on first run
[email protected][email protected]i did 5 runs in total but missed 3rd on 2 runs.
in one race i beat an audi rs6 (07 plate) he ran
[email protected]and in another a C20LET powered nova blew up at half track while chasing my heels.
i was struggling for traction all through 1st and 2nd losing a fair bit of time, i let the tyre pressures down in order to fight tis but was struggling having to feather the throttle through the first gears and my rev counter gave up so had to rely on the shift light for gearchanges.
havent had any time to do anything on the car for a while as;
mums Saab broke down and i had to fix
girlfriend's Saxo wanted servicing
mates golf needed wheels and tyres swapping (8 in total)
head gasket on a friends Corsa
friends FRST broke down (fixed)
brothers Audi wanted 2 new CV joints
service and mot prep on mum's Saab
Coilovers on mates Astra
sometimes i hate being a mechanic!
but finally got round to drilling all the bolts for the cage and re-inforcing the cage mount points so some progress has been made. i have bought a carbon roof to go with the bonnet. am having a garage clearout tomorrow and we'll see what i have to put on ebay and ill get the six-speed gearlever mounted up tomorrow and when the roof arrives i'll cut the roof out.
i'll get some pictures up soon as i remember to take any, and soon as the carbon arrives
well, managed a bit today. got up early and off to the scrapyard in search of a focus gearbox mount, no luck. but did find a mondeo mount, which i didnt know but also fits the gearbox and even easier is that it simply bolts into the mondeo bay as opposed to the focus which would have to be cut from the shell. bonus!
continued the stripping taking all the mock-up parts back out, and removing the air-bag control unit and bracket and all sound deadening from behind the heater. steering column and pedal box were also removed
the engine bay was stripped ready for the engine to be swapped over stripped so that only the engine and gearbox were left. at this stage the inlet was fitted to check for possible solutions to not being able to fit the gearbox with the brake servo. so to see if various master cylinders would fit under the inlet.
also finally got round to making a template to send to mike @performance trim for my bonnet.
and took a quick photo of the BIASmotorsport headquarters
and a little teaser of my mates project
anyone tell what it is?
