Been very short of time over the past week or so, only just finding time to log onto here and update with a little bit of progress.
Started off with the Parcel from Europe I had been waiting 8 weeks for, it was certainly worth the wait though. RTD Tall Race shifters with a custom Duel Sheer linkage. They don't normally make them for the 330i but pointless spending so much on a shifter to mount it to the box with an old crappy linkage...
Out with the old... In with the new, taken the usual theme here and replaced as much as possible. also replaced the push rod on the end of the gearbox and the linkage pins too.
Polybush gearbox mounts fitted up too. All Poly mounts on the suspension and Engine are 90 Sha rating which are the hardest you can buy the polybush mounts in.
The flange adaptor plates I designed come back from being laser cut, I just needed to do some final bits to them, the Exhaust studs are M7x1, just had to thread them all the way through and grind the studs to the right length so they didn't come through the other side of the adaptor
One done, just the other one to go then they can be bolted to the manfiolds then onto the engine.
What a job that was! Took a couple of hours to get the adaptors bolted to the flanges, then the whole lot bolted to the head. All new Genuine BMW studs and Copper Nuts used.
Another bit mark post achieved, was finishing off welding in all of the plates for the cage, strut braces and eyelets for harnesses, this took a good 4 hours welding, really neatly done with all little plates used to fill the gaps between the cage plates and the floor.
With that done the car went off for an Exhaust made from the manifold back. I'd already fitted a V Band to the manifold before it was fitted to the car. Great bit of Engineering, no silly sleeve joints, no exhaust pastes of gaskets.
Exhaust fitted with two longer straight through absorption silencers with a straight section in the middle where another box can be added if required. At the moment it's loud!
Nice twin outward rolled exhaust tips to compliment the full 2.5 stainless system. Will get a better photo of under the car when it goes for alignment.
Cleaned and sat on it's wheels properly to give a good idea of the ride height, nice to give it a good wash to remove all the dust that's gathered on it over the last few months.
Had a few little gremlins this week with the electrics which a few people I've spoken to know about, but it's all sorted now after a few long nights fault finding when it refused to start when all the wiring was plugged back in. The main relay wasn't being powered by the ECU which meant there was no power to injectors, coils or fuel pump. In the end, all earths checked, wiring and fuses but still no luck.
In the end I thought I was an Immobiliser problem so cracked open the ECU. Completed flashed new software version onto the ECU with a few tweeks like Immo delete to see if it fixed the issue. No change.
Sourced a spare ECU from 5 miles away and tried that still no change.
After a few hours Tuesday evening fault finding the tracing wires the culprit plug on the ECU wiring was found which is possible be plugged in backwards! Yes I know! We'd had this part of the loop apart to figure out which of the 4 Lamba plugs we were going to use with the new manifold section. Swapped the plugs around and started first time. Just took a lot of problem solving and brain power to get to the bottom of it.
While we had the ECU out and new software flashed onto it a few changes have been made now. Immo Delete, top speed restriction removed which means there no lower Rev limiter if the ABS isn't plugged in or working.
Also adjusting the drivers request map/table for the throttle to improve the throttle response.
Leaving it at that for the time being until it's been driven on the road. Still got to Raise the Rev limiter to 7K - Doesn't sound high compared to the Clio but the standard engine on these starts to run out of puff at 6K but with the changes should make power all the way to 7K now.
Will also adjust the Cam/Vanos tables to improve the mid range torque but want to get some miles driven in it before changing the maps and making too many changes.
