My 3B project (ongoing)

65535 is serious, I had that when I had a crap chipswizard map from when I bought the car which gave an invalid checksum.

Has the car been chipped? could be the chips aren't in properly.

[Jamo]

The definition of 65535, be worth checking your earths as well

65535

Control unit faulty 1111 -Earth connection to J220 contacts 10,14,19,24
-Control unit faulty -Engine does not start
-With ignition on, no voltage at contact 37 of J220 -Test earth connection of J220

Jamo,

The ecu isnt chipped but has a base map to suit the turbo from Hoffer.

Maybe being slightly stupid here but it is Monday morning but is J220 the ECU?
Obviously the engine starts okay but somethings not right.

Damn, that's some beautiful wheels!

Hmm thats chipped to me. as the s2 doesn't have flash writeable memory but eproms so if the map has been changed you've had new chips in it.

Yes J220 is the ecu

I guess I should get hold of Richard (hoffer) then and see what he says.

In regards to the other error codes I guess a new Knock sensor and lamba sensor is a good place to start along with the boost leak test.

Anyone had any issues with the GSF parts or should I look else where?

[Rusty]

Clear the codes and drive the car for a bit, then re-check. Some codes might be historic?

Fair point, sould have done that yesterday

[Rusty]

Disconnect the battery or pull the motor fuses for an hour or two, that'll do it.

Then take it for a decent run, so it can learn any trims required etc. before checking codes again.

A £5 lead off Ebay is perfect for this, if you've not got anything.

Rather than buy new, getting some known working (no codes!) parts are one option, although, as with even new parts, there is the risk of the parts being faulty. The other option is to swap your parts on to another car, although the more mods you have, the more difficult this is...

What do you mean by a £5 lead?
Ive got a cable that attached to the ports under the steering wheel if that what you mean?
Dont suppose you know where I can source a boost leak kit do you?

Could be one of his other maps, that has had the boost limited if its a base map, but not the checksum corrected?

Dipstick issue

My dipstick seams to pop out every time the car is driven hard.
I have a catch tank installed so got rid of the original hoses but guess these systems can also get blocked up too.
Is my best plan of attach to pull out the breather pipes and give them a good clean? Is so what's the best way to clean them?

Any other thoughts would be useful too.
