AEM EMS 2.3 6bolt/2ghead

[lccynmbr13]

Installed my AEM EMS with 5 bar map last week. The map that comes with the system wouldn't allow the car to idle. It would start and then die almost immediately.
After quite a while of tuning we were able to make it idle and drive yet it would die when coming to a stop unless you feathered the accelerator with no knock while driving in vaccum. Once on the dyno we pulled the intake and ran the car NA to get our base tune before using boostcomp to tune positive pressures. With no boost the car would knock around 5k rpm regardless of whether timing was pulled or fuel added.

Here's the current setup

2.3 6bolt/2ghead
100mm crank
fp3 cams
walboro 255hp
t25
450cc injectors

I know the setup is ridiculous but this is the last phase before the turbo, intercooler and 1000cc's go in and it's my daily driver so I need to get a safe tune for now.

I've searched the AEM customers calibrations section up and down for a map to try and have had no luck. Does anyone have a similar setup with a map I could try to use? Any suggestions as to why this inexplicable knock keeps appearing would be great too.

Knock control is set very conservatively I'd like to hear what others are running for knock control and what is considered safe on a 4g63.

There's hardly ever a time that one persons map wil do naymore than just get your car to start.. especially with large injectors. The 450's should be easy to dial in, but them thousands are going to be a full tune of their own. DOnt expect to tune to 450's then jsut throw in the 1000's and pull the same % of fuel globally and expect it to work.

The large injectors will perform much differently (not just in flow) so you will have to re-map th eentire fuel curve. IT would be best to wait till you get EVERYTHING together and then tune it. The AEM is no "easy tune" system, so you might as well only pay a tuner once and save that extra 4-500 bucks of tuning money for some parts to go faster
Stock turbo, injectors and intercooler but you have an AEM in it already??? That's competely bass ackwards, but i putan autronic on a stock DSM before when we were trying for a record setting pass on a t-25...we never got it

just use the timing curve provided in the base map..then set the AEM to "auto cal" and rive it around "lightly" don t' go wide open till some one who knows how tunes it or you might just have a 2.3 "parts motor" when your done. Or get a wideband and start a steep learning curve. shoot for 11:1 wide open and 14.7 - 15:1 when cruising and idling.. but there's a bunch of stuff like idle stepper motor posistion and stuff that ALL neess to be setup in order to run decently.. there's really no "good enough" tune when configuring a stand alone from scratch, you need to tuine it and tune it right or face consequences.
