·Hi,
I know that this topic has been posted up several times before, but here goes anyway. I have ordered the GReddy Profec B boost controller. Now, I am aware that when increasing the boost I need to be careful of a number of things:
1) Fuel Cuts
2) Increase in temperature
Anything else?
Now, my question is: What is the maximum boost that I can run my car (EVO 4) on, WITHOUT getting fuel cuts? . I want to avoid fuel cuts as much as possible because I know that this is an indication that the car is running lean and then detonation reveals its ugly head. I have heard that it is around 1.3 bar? So running max. boost of 1.2bar should be OK? (Assuming the outside air is not too cold).
Also, would I be correct in saying that the 'wisest' way to get around fuel cuts it to replace the factory ECU for an aftermarket one? Such as a Motec or Apexi Power FC?
With an increase in temperature, is the standard intercooler sufficient to keep temperatures down say running at 1.2 bar? I have a standard turbo too?
Lastly, I know of some cars that:
1) Keep the factory ECU, with a boost controller, OR
2) Aftermarket ECU, with boost contoller, OR
3) Aftermarket ECU - and ECU controls boost
Which the is better option? I mean, is an aftermarket ECU sufficient to increase boost? Or should I still get a boost controller too? I may be thinking of running a boost controller |PLS| aftermarket ECU (Motec or Apexi). Not sure? So, is a boost controller necessary with an aftermarket ECU? Thanks in advanced.
