groovy whatever you have no clue what you are talking about. keyboard tough guy. you should have facts about what you say before posting.

 

I also started out with a basic setup from Scott Gray, he has helped me out ALOT with learning all the features and settings of the AEM. Agree there are definatly AEM settings that should be shared by most users... knock sensor settings, basic boost comp settings, coolant trims, ect.

I think the most important things with the AEM is to enable the knock sensor ign retard and set if on the conservative side while your learning how to set things up.

The AIT sensor I have installed, but I don't have any of the fuel or ignition timing maps changing anything by ait. It doesn't do much good to be trimming your fuel and ignition maps with ait when the base maps arent' even set 100% perfect yet. Im still working on the basemaps but IMHO I think my car runs very well for the mods it has. All street tuned, but it took a good amount of time.

Id be pretty wary of selling an EMS to a customer who is not willing and ready to put the effort into learning how to use and tune themselvs. That situation just seems all too likely to be destructive to the customer and a pita to me.

 

99% of what I know about tuning and cars I either read about or was shown by others. Its only very seldom that you think up an original idea and in most cases even when you do someone else throught of it first.

I am proud to have the opportunity to learn from a master like David Buschur. Not only is he a great example of a tuner, he is a great example of a business man as well.

When you reach the point where you think you know everything - then its time to retire

 

well said

 

you should have fcon v-pro

 

i personally think shiv is pretty great tuning piggyback and standalone, he knows his stuff

 

everyone has there own opinion. that does not mean that al is less of a tuner than shiv. how fast did vishnu go again in the quarter. no wars here just that al is a good tuner. people like you that dont know him shouldnt say things that are not true.

 

 

I was not going to post in this forum but you know what ,,, here i am. I Tuned ricks car back in May of this yr. Ricks car was making over 400 hp on pump gas on the stock motor. There are two sides to any story, and there is a cause and effect for what happend. Rick is by no means easy on his car and how he drives. Maybe rick has since gone somewhere to tune his car from may but as of this point i'll assume he's talking about me. I've reviewed both ricks calibration file and log files and found absolutely nothing wrong with them. He was running 4 degrees of timing at peak boost and 11.5 by 7k. I did not just tune this car last week , something happend other then " i blew up his car ". His log files show less then 1 volt of knock accross the board. Of course he took it somewhere and they told him right away it was his " timing and fuel maps " i believe. His fuel was dialed in at 11.2 afr , and i have his dyno sheets. This is the first im hearing of this happening and was not contacted by rick about this.

People are always quick to blame anything that happens on the tuner or whoever worked on his or her car. Fact of the matter is , when you look at the facts in every case something happend to cause the failure. In one case the customer altered his ignition map , resulting in engine failure. In another case the person was tuned for pump / race, went to the road course after 6 events , had no race gas and just ran pump, with stock heat range plugs.

When you are making over 400 hp on pump gas , with stock evo pistons, all it takes is a bad tank or get a boost spike and you will have a pre-ignition condition. This will crack the corner of the pistons as i suspect rick did. Mitsubishi designed the evo piston top ring lan very small. Much smaller then its predicessor the 4G63 Talon piston. Why , i have no idea. It is a much weaker piston.

Pre ignition detonation is a condition caused by an uncontrolled fuel burn in the chanber, effectively bringing the burn to an end before the piston has completed it's compression stroke. No longer is the fuel burned, it is an uncontrolled explosion.It is extrmely destructive, temps can reach 18000 deg F, and the resultant pressure reaches several thousand psi. This can destroy ring lands. In order for a knock sensor to pull timing it has to see knock. This would happen after the pre-ignition or detonation. IE the damage was done. At 6000 rpm if you get 1 second of detonation you have 100 of these pressure strikes on top of the piston, this all can happen verey quickly.If you run the car low on gas, have a bad tank, or perhaps you have set the boost a bit high, calamity can strike. While some evo tuners will say they turn the knock control on, they effectively cut it's effectiveness by only allowing it to remvoe a single degree per volt

Show me an evo that varies 10 degrees of AIT, there is no change on the evo. Cold starts and settings can be setup through coolant temp sensor.

I've ems tuned about 200 evo's and lord knows how many other cars, from a 10.5 twin turbo pump gas tuned nsx to pro fwd cars to 1000 whp supras. I def have an solid understanding of how it works and know how to tune. There is always a reason for something to happen, the car was setup right and i'll challenge anyone who says otherwise. I have both ricks log file and calibration file for anyone who wishes to see it.

I know rick has been around for a long time in the dsm community, but owning an ems box is very diff from a vpc / afc. A great way to see how your car is behaving / running is monitoring your spark plugs. If anyone is going to make the move to get a stand alone system, get to know it. Get to know your car, check your plugs from time to time. See the burn on them, check for detonation, learn how to read signs. Plugs are the lifeline to your car and how it runs, knowing and reading plugs you will learn alot.

I have had plenty of customer cars that come in here blown up from other shops. These were all swept under the rug as they say. I chose not to bad mouth rick or anyone else in this thread. I have always gotten along with rick and thought we were friends. I would of thought if he had a problem with me or how he thought i tuned his car that he contact me directly but i see he chose a diff path. If im not the person who he is talking about , i apologize for the above. I did try my best to please rick with his tune, from reading on the boards and the amount of tickets he got, it def looks like he had fun up until now.

Sorry for the long exhausting thread and happy thanksgiving.

I bet you the 7 or 8 evo owners who's motors blew up wish the "so called tuner" who fried their motors called someone who knew what they were doing when that "unmentioned tuner" decided to pick up a laptop and start messing around with fuel and ignition maps.

 

further more the EMS is so unregulated as to who can tune them, and with ease of instalation that it is like giving a loaded gun to a 7 year old.

 

I don't want to be brought into this and I hope your not refering to me, because I have never been tuned for racegas and I use NGKBPR7ES plugs and I don't change the boost from what the tuner set it at.

And PLEASE don't insinuate that it's a good idea to tune without a AIT sensor or knock control. I called around 8 tuners after I destroyed my motor and not one of them recommended either situation.

Also, for those of you who get dyno tuned, especially on one of these cool winter mornings. How much stress are you going to put on an engine? If your tuner turns up the boost and ignition timing and then ramps it down once he see's knock after a dyno pull, what do you think the consequences are if you know how to drive and heatsoak your intercooler? Your AIT sensor is after intercooler for a reason.

 

good point

 

I have no idea who is right or wrong here, but big props to Mark at TT for addresing it head on. A phone call was due prior to this thread. No doubt. If things were not resolved after that, then post away.
