I am having a very strange issue. Car has a tuned base map with 240cc injectors that ran well on the car before I decided to do another build. I still have the 240 cc injectors now in the car just to get the car up and running. Setup consist of 84mm GS-R COP, CBR coils, crank sensor /cam trigger sensor ATI Race dampener and CTR cams. The car will start up fine and idle perfect when cold. Once the car IAT gets to 160 degrees the car begins to misfire and idle gets lumpy. When giving the car gas it continues to sputter. The only thing I have not done is sync the timing. I am not experienced with AEM so just need a few suggestions as what could it be if it’s not to related to a timing issue. I have been having issues trying to sync the timing because I am not getting an accurate reading. The timing is jumping all over the place. The car starts running bad when it gets to operating temp. Ign Phasing is set as listed below.

Ignition Sync 1.53
Pickup Delay 150.00
ign tooth 01 12.00
ign tooth 02 6.00
ign tooth 03 18.00
ign tooth 04 0.00

I would appreciate any help. Thanks

 

if your not experienced with aem software then get it to a tuner pronto before you pop the motor. its not an easy system to work with especially if your not experienced with it. And aem has to much to learn for the novice tuner. Ive used it before and i tune and still had trouble with it a few years back

 

I understand that. The car will be going to a tuner, I just want to know if timing is causing this issue that I am currently having. The base map was a tuned based and nothing has changed with the tune.

 

there is no such thing as a tuned basemap. a basemap is just that and a tune is a tune. the timing can cause problems but i dont think thats yrou issue and you need to not be driving this car till you get a real tuen on it. you should NEVER boost on a basemap or even try to drive to much

 

Yea. I haven't driven the car. Thanks for the advise.

 

Good luck, try to sync your timing anyhow but again i dont think thats it, just sounds like leaning way out
