EVOscan Is it necessary to tune to 80% IDC max?

[_Madman_]

I have stumbled upon few places that says that 80% IDC is the max you should have at any given time. One of them is EvoScan IIRC.

But I have also seen that some members run IDCs in 90ies...

I'm about to do some tuning in tomorrow or day after tomorrow, and I will have to set my boost levels to a safe value.

I have 14b, Walbro 255+fpr, and the bottleneck - 450cc injectors.

I was planning to go towards 90%-95% IDC @7k RPMs, 3rd gear pull. But maybe I'm completely off the charts being a newbie...

I'm going to use EvoScan for tuning, and I have an MBC for boost adjustment.

80% IDC is safe, but you can go higher.

If you get close to 100% and you have like a boost spike, or a little more boost on a cold day, you may not have enough fuel to compensate.

I wouldnt recommed it. Injectors that stay open and almost no time closed have a greater chance of either burning out themselves or worse, burning up the iniector drivers contained within the ECU

Plus it can make the AFR unstable due to the injectors being open pretty much all the time.
