huh? thats what i said too.


my buddys bluebird swapped b14 is having this problem right after his fmic was installed.
he is also loosing a bit of coolant on long drives, but we cannot for the life of us find a leak,

we checked the fuel pump and changed it out, no change.


im not sure as to all the mods but i will say
bluebird stock, except for cams
255 pump
fmic
aeromotive fpr? i think.
aem wideband

any ideas?

How are you monitoring AF? I am assuming it is running leaner than it was prior to the install? It would also be helpful if you shared AF ratio's throughout as well.

You do realize hat it will run leaner in that range depending on throttle position than at WOT right?

Also what do you mean by loosing coolant, is it no longer in the overflow? The coolant system draws from the overflow under normal operation so the level will vary...

yes we are monitoring the a/f it spikes while the car is at a steady speed. like 12 and then up to like 14, as for the rad im not sure as to what the problem is exactly, he said he posted the same problem so im going to look for that,

mods can close this, he posted with much more info on the problem.
