Bring it in i will take care of it for you.

There you go Ray,right from the Man himself....

 

i will call you later on today!!!

 

David does do a great job at tuning. My car started fine even after I left it sit in an unheated building for 5 months in Ohio winter. When I did start it was about 10 degrees and it fired right up. I have seen ALOT of my customers with the same experience with their car after David tuned them. Its all in the tuner and the tune on how the car is going to run. There are VERY few complaints on his tuning. A good tuned standalone should be similar to a stock ECU car.

Cold start for some does seem to pose a problem but he has it down to a science.

Well.... we all know you have to have at least that one ignorant comment in a thread here to start to kindle a fire. It just wouldnt be EvoM without it.

David doesnt tune for peak power. I guess if thats the case we wouldnt have autocross and road racers blazing around the tracks / courses and taking home awards would we? He can tune for whatever the car is going to be used for.

 

My cars running great with Sean Ivey. I have revolver's and my idle is very good. Cold start is not an issue with my new starter!!! I killed my starter fast. I've had AEM for 40k miles already.
AEM is suppose to be smooth.

 

i just had a bad spell of cold starting. i am contacting buschur racing monday to find what it cost for a cold start tune. im already making plans to go there from kenosha wi with my wife. i need this prob taken care of imediately before my starter goes out or something else messes up.

 

It'd be a lot easier on the starter if you turn the key on, wait for the pump to prime, then try to crank it.

The box won't sync till after the pump has primed.

 

A little off topic:

If I get my car tuned using an AEM in 20 degree weather, will I need another tune for it to run correctly and safely when it is 80 degrees?

 

If it's tuned correctly and proper air temperature correction is set, the ECU will know how to compensate for the change in temperature and you should see no difference.

Your scenario I have experienced as my car has cold started and ran (in boost also) in low 20 degree temps and ran no different days later when it was mid 80's. Got to love Florida winters!

 

I've heard that part of the cold start issues are related to a design choice (not flaw) for the AEM in how it senses crank position. It will always take a crank or two more than the stock ECU to turn over, but with a good tune it should not be an issue.

 

Thread started off a little rough with that confusion on who tuned who.....glad it got straightened out.

I am not saint (no **** right?) I do the absolute best job I can on each and every car I tune. With that said I haven't seen a perfect tuner yet and some that shouldn't even be allowed to attempt to tune.

Cold start in the beginning was a complete PITA. The biggest problem were settings in the AEM base files that were done in California where it is never cold enought to matter. The base files are still not correct. There is only one way to ensure that a car is going to start under XXX conditions and XXX tempurature and that is to start it in those conditions. If it isn't started in those conditions there is no gaurantees that it will. Why do you think OE manufacturers have hundreds of people working on OE tunes and such in the desert and Arctic?

The AEM honestly has some issues anyway that make the matter worse. As was mentioned the fuel pump priming is one, the cam/crank sync is the largest one. Non of this helps cold start ups. Some of the things that have been listed over the years to help with cold start are complete BS and laughable now. They should be "unstickied" from EVOm actually.

Here is what I see. Just about all of us here drive EVO's and they all have AEM's on them. It also get's very cold here and in the summer very hot. So we have a climate here in Ohio that ranges from below 0 to over 100. It gives me a lot of chances to get all this crap right. Am I perfect? Again, no I am not.

I just went out in the shop and asked Daniel, my brother, how his car has been starting as he is the only one who drives his all year round. It has been down to 1 degree lately. He said his car has been starting no problem and smiled. This morning for example it was 9 degrees.

Now, we all use the same injectors in our car, which is a huge help in all this. Trent, Daniel, Jarrod and myself all had 1,000 CC PTE injectors, gave me a ton of time to work on each map over and over and over again. This has contributed greatly to the success. Daniel is running a stock turbo on his car now and still has the 1,000 cc injectors in it and the "same" map we use for all of them.

As for the OP's car, I'd be glad to tune the car for you, I see it's got quite a few of our parts on it anyway. Bring it over.

 

That’s pretty funny being said out of your mouth because the last dumb comments you made were scrapped within a few min from a evom thread. Also I just happened to fix a Buschur AEM tune a few weeks ago. Not for starting problems but decel and low rpm fueling issues causing drivability frustrations. That wasn't the first one I had fixed or given recommendations to either so my comment is justified in my opinion. I don't expect everyone’s tune to be perfect as long as they can admit that and be open to try and fix the problem.

 

IN intrests of full disclosure, who did you retune, and what sort of changes did you make? Have you noticed spontaneous changes in the warm up enrichment table in your EMS? mine has been acting fubky lately.... either new maps are not being saved, or it seems as if the EMS randomly reverts back to older maps... which should be impossible...

 

GTVEVO, I won't argue with you. 90% of the guys that we tune and build are from out of state. You re-tuned a car or two that I did, good for you, hope the customers were happy. I re-tune multiple cars on a weekly basis from other shops. Guys you re-tune will end up going to someone else too. It happens. It use to bother me but now I don't let it. First of all, if a guy comes here from out of state (like I said 90% do) that means they had to drive atleast 2.5 hours to get here. Some get shipped here from all over the country, Texas, California, Florida, Main etc. I cannot get mad, offended or even defensive over a guy who needs to get a tune touched up by someone else. As I said, nobody is perfect, I certainly am not.

I can tell you it's easy for someone to sit back and talk about their re-tunes on the internet and steal well done maps in the process. That I can gaurantee. You "fixing" cars I've done got you kick *** base maps if nothing else with no ground work on your end to figure out and fix the multiple problems AEM has. No thanks needed though, you are welcome.

 

Yes,I can recall having an AEM for sale a while back (2 years ago) with a Buschur tune in it and I had more P.M's asking for me to download the Map and send it to certain members to "verify" if in fact it was a "Buschur" tune.I was not born yesterday so I just kindly replied for them to buy the AEM and they could find out for themselves but guess what? None of the people who P.M'ed me about the MAP wanted to spend the $$$ for the AEM as they only wanted one thing from it,a Free Map to use for their own personal gain. When I ended up selling the AEM I did the right thing and spoke with the buyer about what he wanted from the AEM and ok'ed that I would download a "base map" and load it to the Sold AEM and put the map that was removed from the AEM in the Recycle bin.The person was buying the AEM for the AEM and not the MAP as they were going to have a "local" shop install and Tune it. That being said I felt the map in the AEM was not needed by "another shop" as each tuner does their own thing and if they wanted their maps to be "public domain" they would post them all over the internet.
I had no use for the map then or now and it never was given or used by anyone.
Each tuner has his own way of tuning and their own things that they alone do and that must be respected.Like posted in "quotes" above I am quite sure that many people take other tuners maps for their own gains.
