AFR,S and fueling evo 4

[rst]

hello all, do you think the standard ecu on a e4 will fuel ok to 1.2 bar? are do you think it will run a tad lean, its not a massive amount of boost

thanks

A tricky question as I have personally seen an Evo IV handle 1.3 with no issues and I have heard of one from a reliable source that was running 1.7 with no fuel cut

What I will say for sure is that ECU's are not my strong point but I guarantee you that if you click on this link below and post your query there, a friendly member or two will be along to answer your question for sure.

Friendly members that I think you might already be acquainted with

Here is the link buddy:

To be honest pal before i changed to e5 ecu and injectors, My e4 was pulling very well indeed and over 1.3bar on hks boost gauge And had no issues what so ever,,

As said get the fueling and knock checked to make sure its ok but i would have thought it will be i have done a E4 running 1.6 bar and its been fine for 2years it is on E5 ecu and injectors though
