Re: Compatible Smaller Injector than Bosch 280 155 777

Have you cleaned your MAF?
Carby cleaner or contact cleaner will work ok.

A dirty MAF will over-report airflow and cause the ECM to over-calculate fuel.

Re: Best Camphase to suit engine's

That bump in compression alone will make a massive difference in performance!

What lobe separation does the cam have?
For it to close the intake at 81*ABDC, on 105 ICL would take 312* duration, that sounds like a huge advertised duration for a 224*@050 cam.

Re: E38 PCM Locked

HPT & EFIL can both lock the pcm. Using a patch or Custom OS in either package will make it inaccessible to the other.

Re: First fire up using Rt

Somethign doesn't see to add up.
That last bin VL400 posed now has your injectors scaled to 60% of your $A5 tune, but your VE is only scaled to around 80%, so it should be much richer.

Is your wideband reading correctly?
Did you take a log of the $A5 memcal installed that you could compare against.

The ecu can't limit throttle opening.

If it's not reading 100% when you have pulled the blade wide open then there is an issue with the TPS.

Is this a NA car converted to L67?

Re: Whats the best boost AFR

How is engine load different at 100kPa for a boosted vs non-boosted setup?
At 100kPa the same air mass will enter the cylinder, irresepective of a charger being able to deliver more.
