your answers are a bit contradictory. Are you saying that the car cold start is fine, and may start if you pump the throttle during hot start AND the stat sync is not on??? I don't see how that is possible.

The AEM requires a well charged battery. It will also take a few cranking revs to engage the Stat sync. Could you try it again? If you get stat sync then all you have to do is play with your start fuel vs temp offset table. It would be easier to adjust this table with a wideband but without one it's just trial and error.

BTW what plugs are you using?

 

ok, when i drive the car and the motor gets warmed up, and i turn the car off, it will not start for about 30-60 min. After it has sat there and cooled off for that 30-60 min, it will start up fine. After i get done driving, if i try to start it, it cranks really slowly. After it has sat for the 30-60 min., it cranks normal. When i try to start it after it driving and it has sat for a while, giving it half throttle while trying to start the car it helps it start.

 

i forgot what plugs, theyre ngk ???? ill check when i get home. They are gapped to .30

 

your cranking fuel on your tune is off. check that.

 

It looks like you may have 2 problems; fuel and crank pulse.

Fuel issue:
Hook up your laptop to the car when the engine is hot and you have problem with start.

Start with Warm up enrichment table. You will find this table in
-Engine Start
-Warm up enrichment table
-Graph
-hit space bar to go to the temperature of the engine
-subtract 5 points and try to start, if it doesn't start try this process afew more times. If the car doesn't start go the opposite way. Then try it again at some other points on the graph (ie with different engine temp). Then just smooth out your graph.

If this doesn't change anything, put it back to where you start and play with the Start Extra vs Temp Table. You will find this table in Engine Start, Advanced Start submenu. Do the same thing as above. (Edit: Sorry work is busy today so I got it the other way around Try this one first and then the warm up enrichment table)

If this doesn't work then go the Raw injector Vs Throttle (or whateveritscalled...sorry I could not remember the exact name off the top of my head). Do the same thing again at 0 % throttle.

Make sure you have a fully charged battery during this procedure. You will also need to crank for a few seconds for each try.

If you have a wideband it will be slightly easier.

Crank Pulse:
Compare your map with the supplied map from AEM and change your Initial crank pulse values back to stock if needed. I've not change these values in my map and I doubt that you need to change them. I think you will need to increase your Crank pulse values with the warm temperature. If your value is the same as the stock then I suspect the crank got slower because your battery voltage & current dropped with repeated cranking during difficult start.

Good luck and have fun...make sure you have some paracetamol/aspirin handy

 

Did you solve ur problem?

it happened on my car everything worked normal until one day the transistor for coil 2 went out so I switch out all the transistor and drove it for at least a year and a half with out any problem, recently I just rebuild my motor with my stock ECU and then plug everything to AEM once the break in procedure was done, (every first time ,start up is prefect when cold 2 crank and it start right up every single time. after a few pulled on the highway, the car die and I couldn't restart the car again ( i plugged it back to Stock ecu and it start right up so I am sure the engine component is good ... but once I drove it for a while and then restart again, it won't crank over. stat sync won't turn on and SYNC ERROR and TIMING ERROR KEEP counting as it is cranking.. I believe it is the 1050 box issue .... I logged T2PER,Crank tooth , SYNC ERROR, TIMING ERROR , RPM , o2 when very first start up (fire up) and the log when it won't start...would someone give me a hand .. I am lost... thanx in advance !

 

i am having the same problem.
i have a 1052 u. when it is cold the car will crank and start fine, but when warm or hot it just would not start? i tryed everything grounding, timming, fuel, ect...
i am lost. i am going to send the aem back to get check.

 

also, i am getting a hard spot, a glitch when cranking. like it cranks then it hits a hard spot and seized the cranks again>>>
so werd

 

did you ever fix this problem? i have the same problem with my aem ems series 2

 

We had this happen on a customers car as well. There could be something wrong internally with with older boxes. The customer would not believe me that it was the box. He then took it to another shop and they couldn't figure it out either. They ended up sending the box in to get it fixed. The Aem V2 stuff is amazing, the older stuff is a PITA.
