Re: DIrtyTorque's odd corner.
devil makes work for ilde hands.
I have ran some chromel and lumel egt wire closer to the EGT chip in the hope of getting rid of noise in my EGT signal that is displayed on the laptop.
Tested it first with a hot air gun and then i got the blow torch out.

Seems pretty stable.Fairly happy with that.
Will check how it performs on the car.

Re: DIrtyTorque's odd corner.
re-fitted exhaust manifold along with new lambda probe in its new position.
Was running on 3 cylinders,one of my spark plugs has died.Swapped that with one I had lying around for now.
Very happy with the new lambda guage too.It will be nice to have that info at a glance.

Re: DIrtyTorque's odd corner.
wired up the second slimline fan so that it is now in parallel with the first one.It's a big radiator and so needs the larger fan coverage.
The images below show me testing my soft start pwm fan driver circuit.
Basically instead of the red-white/black/red stage 1/2 wires turning the fan on directly they just power my fan controller.The positives of the two fans are permanently connected to battery positive and the power transistor switches or rather pwm's the negative side of the fans to earth when the pwm circuit gets power from the fan switch operating.
The soft start works beautifully.Quite proud of that actually.The fans have zero effect on the engine running or lights etc upon fan start up as the circuit pulls very little current to begin with.Once it ramps up the two fans really do shift the heat.The heat coming off the rad through the fans is quite impressive.The fans thus do not have to run for long.
I let the system cycle four or five times.Regulates the coolant temps really well.This system will not interfear with any of the factory features like the after run and works alongside the fan controller unit.[You must be registered and logged in to see this image.]

Re: DIrtyTorque's odd corner.
Did you create the PWM signal using discrete components, or using an IC like a PIC?
Re: DIrtyTorque's odd corner.
The actual circuit will be tiny this way,easy to stash away somewhere.
Want to start on installing a knocksense box next.
I have also found a 3 axix acelerometer chip.I thought that could be interesting.
So many toys so little time...

3-axis accelerometer sounds interesting. We have a body control module or two that use chips like that. They also have integral Gyroscope.
Is that the KnockSense kit that has been 'knocking' around, or one of your own doing?

i'm going to try the out of the box Knocksense kit,designed by some chap in the US.I still have some HP knock chips though if I did fancy having a play at something more custom.I still have those strategies that you sent me I think.If the knocksense units give some measure of functionality then I won't reinvent the wheel.

Can you knock me up a little circuit that switches an LED on for a few seconds when it first gets power, then goes out?
I can't be bothered to try to fix my ABS.
Ahahaha! Nice to see you're still at it Rob. Any sign of a turbo yet? Nice idea Tom.

It's a case a when not if, although me and tash have split up so I am re-evaluating my finances att.Not sure how much disposable income i'll have.

Is that a turbo as well or instead of the G-lader Rob?

Hmmm...
I think i'd like to try and keep the larder.Or at least prove to myself the folly of twin charging.
Have you considered it yourself?

Re: DIrtyTorque's odd corner.
I'd have a big turbo under the car after your 4-1 and use a 2nd DBW throttle setup in the ECU to start opening at around 4000rpm. It would feed into the g60 IC to TB boost hose after some sort of watercooling. Sorry to hear about your split. Compound charging is an option I guess but how drivable would it be?

Yes I have indeed.
I even considered using the management from the VW twin charger to run it on, although aftermarket stuff with an aircon on/off config should do the same job. It would be a fantastic combo with massive torque and 350-400bhp achievable with a good set-up, you could run a silly size small pulley on the charger as it could be turned off around 4k max and then let the turbo run the engine all the way up to 8k+ for silly boost.
It is on the list of future silly jobs in the really long term, I want to get the most from the charger first.

As I have said to everyone else Chris don't be sorry we were driving each other nuts and have lived seperate lives for quite some time.
We're both happy it's over.Maybe that's the wrong way to say it but I think you know what I mean.
talk about airing your lining in public.
Turbo under the car huh.
A large turbo is a must I guess.Weather or not Id run a clutched system for some high rpm action or just use the same rev range and just fill out the top end torque curve i'm not sure of.
Just crazy talk at the mo.
The next thing i want to get serious about is knock control as I think there are some gains to be ad in this area.If I advance the timing statically via MS I can feel the extra power,but at the cost of the death rattle.It would be nice to be able to sail closer to the wind

Re: DIrtyTorque's odd corner.
Not only that a good knock strategy will enable you to lean back the mixture under cruising at maximum advance safely too.
The idea of a electronically controlled clutch (read air con pulley) to spin the charger up and down does make the most from the setup, you also get the best from the 16v arrangement by allowing it to rev highly, 8k is easily achievable and should give some really good power and torque.

yes the charger does shackle the 16v engine in one respect.I feel like i'm only tickling the engine at the moment @ 0.6 bar.

scuse dodgy images.Finsihing off the pwm fan control cct.Just need a suitable heat sink enclosure.

still just doing light stuff on the car while I try and save money.
Nearly finished my soft start module for my two revotec fans.

Re: DIrtyTorque's odd corner.
connected to the car now.All done.The current supplying transistor has to do a fair bit of work,hence the heatsink,and the heatsink case.
want to look at knock sensing next,but need to change my front topmounts and I want to fit some good wipers.TT or lupo.
I'm hearing the TT ones are the best?!??[You must be registered and logged in to see this image.]

Re: DIrtyTorque's odd corner.
I doubt it mate.It sorn'd at the mo to save money,although i'm starting to regret that.Need some corrado action in my life.
Main focus is getting another MOT ticket on it for another year.
Had a advisory last year about the topmounts so I need to change them out really.
Also want to fit another throttle cable along with some wipers that work.They seemed to be worse than ever the last time I drove it.

Re: DIrtyTorque's odd corner.
Shame would have been good to compare some notes with the cars side by side (assuming mine gets that far )
Spent 10 hours over the last 2 days with a rotary buffer trying to get all the sodding scratches out of the paint, still got the lower half of the passenger side, N/S/F wing, front bumper and sunroof panel to do. Annoying because it was in far better condition when I parked it up 4 years ago..
Then it's an oil change on Thursday morning, a bit of packing and I am hoping the injectors I sent for refurb on Monday will be back by Thursday so I can fit those too.
