I'm running an EMU on a 2004 MSM, trying too anyway. On the stock injector or supra 305's wit work decent using auto tune. I recently switched to RX7 460 cc injectors. I can't get those ******* undercontrol to save my life. Also, I have the issue of the car not running when it gets hot. Seem this damn thing does not like these RX7 injectors. So, I'm thinkning of buys new one.

Setup Mazdaspeed miata, FM DP, FM intake, Magnaflow exhaust, running between 10-12 PSI.

Furture upgrades, I will be upgrading the factory turbo with a bigger compressor, maybe a meth kit later one. Thoughts?

 

if you are going to upgrade your turbo i got the place to send you. these guys can make anything out of your turbo add bigger shaft, bigger housing, different wheel maybe better stage wheel. they know everything there is about turbos. trust me. they fixed up my super 60 and they give you 1yr warranty.

what is the lag time on the injectors? post another file of yours with the new injectors.

 

you really shouldn't go bigger than 330cc or so with the stock ECU and expect to control them.

 

i got 460's and they work fine with the EMU he is also running an EMU

 

Are you sure the injectors are good? Your problem is part related or tune related. I idled RX7 550s with an EMU

 

Same here...460's worked great.

 

It could very well be the part. I should have had them tested before intalling them. I just ordered some RC 440 CC injectors new so I will find out in a few days for sure. I kind of screwed myself. I had some 305 supra injectors I bought used. I had them in the car last year and they ran fine. They were doing fine after I put them back in after adding the EMU. They crapped out on me. The 460 could be crap because I didn't not send them out to be check. I guess that's what I get for being impatient.

 

Which company are you refering too. I'm familiar with deadbolt and Blouch. Do you know of another one? Pm me some details if you do.

 

Were any of you able to get them to idle with autotune or did you manually go in and remove fuel util it smoothed out?

 

I've used mutiple setting for lag, none seem to help much. The setting I get to run although really bad idle is 280 and 460 for before and after and .10 and .96 in the lag menus. What do you have in yours?

 

in the before box put 0 instead of .10 and after put 0.6 instead of 0.96. autotune is not going to control fuel on idle it is a bad idea. all you Target AF values should be - if you are not in boost. all your maps have to have the same scaling.

 

Basically I need to keep pulling fuel until it smooths out?

 

try the suggestions i gave you earlier. see what happens i would not autotune in unboosted cells.

 

read this maybe it will help
