I recently purchased an InlinePro turbo kit and love it. I am using the AEM EMS and have had a few problems. My tuner is telling me that the reason my car is hard to start in the cold is because of the ems. He said it cannot tell the temp outside so it thinks it is always 0 degrees. Which is why it is a pain in the ass to start. Does this make any sense? Would the ECT module from modifry fix this? Or does it just make the dash temp work again? Next question, after going turbo my car smokes a lot for the first 100 or so feet I drive after i first start it up in the morning. I can let it idle 15-20 minutes, but this does not help. Does anyone know what might cause this? I have taken it to the guys who installed the kit, but they can't seem to find what is causing it. Is any rattling noises normal, this may be a dumb question but I am new to turbo kits? Has anyone had any of these problems? I am starting to get a little frustrated at the fact that my car is always in the shop, or can't be driven do to the fact that the bolts that hold the downpipe on keep coming out. Which is another problem also. I have heard when you turbo a car that was not so from the factory you will experience a few problems, but this is getting annoying. Someone help please.

 

I don't think your tuner knows wtf he is talking about to be totally honest. If you hook up a laptop to your EMS and look at your startup tables you will be able to see that your startup and enrichment maps go according to your coolant temperature, which is usually whatever the outside temps are. I would be scared if that guy tuned my car because I know almost nothing about tuning an EMS, and I was able to play around with my startup maps when my car was first tuned and having starting issues in the cold.

The modifry fix will just make the ECT gauge work again, it wouldn't fix your maps in the EMS. As far as your car smoking, what color is it? If its oil, sometimes that is from your oil return being too long, if its not straight it can cause you to blow out smoke, but this may not be your problem at all. As far as rattles go, its always a PITA to hunt those down after an install, but if you had the work done at a shop then have them fix it. Frankly, after reading your post I would be very skeptical of the guys that installed your turbo setup and tuned your car.

 

^ I agree... The AEM system is a fairly nice system and does a good job of retaining normal drive-ability of the car... IF THE TUNER KNOWS HOW TO USE IT PROPERLY, lol.

Even in the coldest of temps with my car just sitting there It doesn't take me more than 2-3 attempts to fire up the car, and it idles perfectly fine... right around 1k rpm after it has warmed up a little.... feels stock. And yes, the modifry fix is ONLY for the stock temp gauge to work with the EMS.

As far as the smoke is concerned, try to figure out what color it is and we would be able to offer a bit more input on that.

I'm basically repeating with XclusiveAutosports said, but he pretty much covered everything...

 

The AEM is plug and play with the stock sensor. The calibration table is a bit off and the base map has completely screwed up air temp and coolant temp corrections, but your tuner should be able to fix that. The gauge is a separate issue and Modifry's fix is a must (IMO), but will not change the reading to the AEM.

With the downpipe bolts- People try everything from tack welding a corner, to using loctite combined with star type washers, to using safety wire. All of these methods can work. I had good success with torquing cold, using loctite and star washers, and then re-torquing after the first few times putting some heat into the manifold (while it's still hot). It took me months to get my downpipe and wastegate sorted out to the point that they wouldn't fall off. After that, I never had any more trouble.

I thought that was what the modifry ect did. I am also thinking I will have to find a new tuner here in town, but don't know any besides the one I went to. Anyone know of a good tuner around Memphis? They have always done great work for me in the past. So sad it has to end this way. Oh, btw the smoke is white. Another thing I meant to ask last night was about the idle. Mine idles fine about 50-60% of the time, but sometimes at a red light it will rev up and down real quick, only about 500 rpms. The air fuel guage will jump from around 14-15 something all the way to about 17.5 and sometimes so high three little dashs show up on the guage. It is an AEM wideband UEGO, if that is important. Atleast I think that is what it is called. I do appreciate everyones advice so far. Thanks.

 

Find someone else!

 

^ x 2 i dont think your tuner did a good job, try to find someone in your area to look at it before you damage your motor in any way.

 

What color is the smoke??? That will tell you what the problem is...
Black, white, or grey...????

 

The smoke that comes from the exaust is white. Anyone have a idea what would cause this?

 

Hmmm, doesn't white normally mean water/coolant? From what I remember, blue is oil so you shouldn't be worried about that.

Did you happen to get a thicker headgasket?
