Smart injection

[Kapt. Q]

Hi Richard,

SC is 1 o'clock, Gain 12 o'clock.

I get quite a surge when injection turns on, if i turn SC down so I can see the surge then it is 6-8 bars+ then it dies down to 3-4 bars, is this correct? (I usually set SC so normal flow is 6 bars (1o'clock)). I have checked the nozzles and the spray pattern is ok and it continues to drink heavily. I am worried that the tank was contaminated (I rinsed it with windshield washer concerntrate, shaking it vigoursly, then Meth/water, then water before installation), perhaps I have damaged the pump?

It is difficult with no experience to know, lol.

Will the surging cause the failsafe to activate? Do I perhaps have a partial blockage? I swapped the pre turbo injector to check, but no difference. Perhaps I should do the same for the post IC nozzle to check it?
The 'O' ring I lost (idiot) in the check valve injector must mean that the intake vacum is drying the lines between the injectors, will this cause a startup surge untill replaced?

I have not adjusted pump pressure yet (can't see the allen bolt but haven't looked hard yet), perhaps this would reduce the surge?

The car is running really well! Did over 100 miles to a VW show and it loved it!

Thanks for your help, hope to get an appointment with the tuner tomorrow for this week, fingers crossed.

Cheers!
