General Discussion / Re: Cossy BOA running lean
« Last post by capri v8 driver on May 20, 2020, 19:05:20 PM »
How is the fuel pressure and the lambda values?

And no there isn't much you can do with the stock ecu to make it run richer. Losing the EGR creates a very lean condition in the mid range of the RPM and the ecu cannot compensate for it.  Some people used bigger injectors or upped the fuel pressure but that opens a other box of problems.

The only way to run the engine properly without the EGR is to use aftermarket ECU.

yes it surprised me that is made so much difference especially the turn in being apparently improved.
I think the toe was 2 mm toe in

Very strange. I ran my car for years with a washer between the ARB and tca to increase the caster, it didn’t give any problems at all.

Did you get the print out with all the alignment angles?

Yes the toe was set correctly, you said earlier it should affect the camber too but the Caster change totally ruined things, as soon as I changed it back it was fine,  even without getting the toe reset

I don’t understand any of the things you mention. Basically you are just increasing the caster, nothing more. Did you have the front toe setting checked/adjusted afterwards?

The change in bump steer should be completely unnoticeable.

I don't recommend this.
it was worth a try, turn in felt improved and steering was lighter but it came with fairly bad instability and shuddering steering wheel under heavy braking and a lot of bump steer, minimal for normal driving but still a little unpredictable

thanks Marc I knew it would change the castor but hadn't realised the camber would also be affected so im going to give it a trial since I was replacing the tca's and reinstalling the rack anyhow and ive had a set of spare washers since I read tonys comments about it years back  :2tu:
