jestr typically has more aggressive mivec and timing map near peak boost, so the torque increase youre seeing is typical for one of his tunes, but the peak power is still pretty much unchanged, at first i though the jestr map might be knocking up top, but the log looks clean to me *shrugs*

let us know if you've done a boost leak, and it may be worthwhile trying to go back to the stock airbox just looking at that wavy torque curve.

 

Since the MIVEC maps are actually almost the same (dont ask how I know, just trust me) between the 2 the reason the power under the curve is higher with the M1 is it has some timing. That other one you posted up is an abortion and honestly I would be pissed if I spent money on it. They took care of the fuel as well as they could and left the timing basically stock. This equates to a waste of time and money. The JestR could be knocking a little or its just the difference in where the logs were generated and atmo at the time (even if similar, small changes can account for 5-10hp).

For the record a hacked airbox is better than that K&N cone, seriously. If the tune hasnt taken into account that the vortices in the KVG are NOT the same as the stock airbox or close (8-10%) its like throwing big injectors in without rescaling. The MAF has to be rescaled to account for the error generated by the airflow changes. Not that I like to sell parts, but honestly of all the cone filters the BR has been the best I have tested.

I may attempt to return to stock airbox. I damaged the box in removing the MAF, so I need to buy a new one.

Thanks again guys

 

The first log posted, was that stock?

you were at -6*, IPW was 23, and AFRMAP was at 200 (about 9.7 in cell). That may be waay to rich.

Only choice is to use a wideband and go from there


You can find an airbox in the FS section, if you cant I might have one in the attick but I'm in Germany right now so I can't check

 

First log posted is my dyno tune, but with stock FMIC.
2nd log is my same tune with my AGP FMIC.
3rd log is my Jestr M1 with AGP FMIC.

I'll be picking up a wideband for sure.

 

Are you sure that your using the correct numbers in the DLL car definition file? when I run your log in my DLL, it makes 288 hp and 286 lb-ft of torque. Here is the car definition file that I am using in my Evo IX. Try it and tell me what you get.

 

For reference, on the dyno4mance dynodynamics we normally get 285 - 295 on an IX reflash with those mods. So it's not super far off. DynoDynamics reads much lower than most other dyno's.

Looks like your boost curve is very erratic that may be part of the problem.

 

I replaced my Forge UNOS with a Hallman and it's holding boost much better.

I'm picking up an LC-1 on Friday and I'll start my own tuning

 

I also have another quick question. I remember reading that when calculating HP/TQ, it's best to log Time and RPM right next to each other.

How do I make the change in EvoScan to do that?

Thanks

 

some people just log only time rpm and knock, and octane. gets it close enough.

 

You have to change the order of the entries in the "Data.xml" file located in the \EvoScan\DataSettings\ folder.

 

Matt did make a few suggestions. First the Torco is junk. It made your plugs change color and did nothing to help with power.

Second, you never mentioned that your compression after you got a reflash from another vendor was in the ballpark of 120psi IIRC. That will be probably your biggest concern.

As Matt says- he gives the motor what it wants to be happy and whatever power it makes at the end is exactly that.

Good luck with the self tuning. Be sure not to believe the horsepower readouts on anything but a dyno. The logging or G meters aren't accurate in that regard. I've seen and heard of disparities up to 100whp.

Compression on an Evo 9 ranges from 92 psi to 145 psi. On an Evo 8 it is 138 to 163. If it was an Evo 8, then yes it would be low, but this is an Evo 9.

The car was running -6 and -7 degrees of timing @ peak boost/torque. Logs were posted and we all saw them. It is the negative timing in the ignition map, that more than likely caused the power loss.

Doen correctly, Road dynos work fine. We use them for before and after comparison and that is all we do with them.

I am willing to bet that after Shamelesscookie is done with his self tune, his car would put more power on YOUR DD dyno than it did when Matt tuned. If that is the case, will you give the guy his money back?

 

Hi Alex. I had sent a few e-mails to Matt lately, not sure if he got them, but regardless.

I do not know what made my car so sensitive when I was tuned at DSG. I am still running the Torco (the orange plugs is a well-known effect, which hasn't proved to cause any problems).

I can tell you with 100% certainty that my tune is now correct, compared to when I left DSG. My AFRs were too rich, and my timing too low (compared to where a custom tune is typically at). I'm not BLAMING anyone at DSG, I'm simply stating a fact... my custom tune was unlike 99% of custom tunes done on Evos, in that barely anything other than some AFRs and the MIVEC map were changed. Is this my car's fault? PROBABLY! But I can't produce the same results Matt was getting, in which he said ANY more timing would quote "knock the car on its ***".

A friend of mine recently got his 00 Camaro LS1 tuned at 333rwhp. We went for a quick pull off the public roads with my DSG tune, and he pulled on me RIGHT away, up to 4 car lengths at 120mph. This is the exact same car I drive today, only with the DSG tune.

Last night, we gave it another go. This time with my custom tune. I torqued him to death and from a 20mph, 30mph, or 40mph roll... he couldn't touch me... I pulled him by 1 car length.

So maybe I'm silly to believe an on-road dyno chart, but gaining 5 car lengths were the difference is only my tune versus yours... that speaks for itself. Not to mention the logs, all of which EVERY EvoM member who's ever tuned a car felt were gross.

Sorry for the long-winded post... the only thing I am mad about is the fact that my car, for WHATEVER reason, wasn't behaving normally the day I got tuned at DSG. is that your fault?

No.

Should you give me the courtesy of re-dynoing with my own tune?

I should hope so.

Regardless, thanks to everyone at EvoM. My car runs awesome now, and I look forward to continue tuning my car.

 

It is not your car that is the problem, it is the tuner or shall I say "tooner." I have dealt with "tooners" like this and learned from my experience NOT to trust them. The "tooner" in question was Tuning Tech in CA.

Almost all of them have big egoes and are set in their ways. Most of the time they do things one way and are unwilling to try something different. They want to make the car fit the tune rather than the other way around. They are always in a hurry since they have to put the next car on the dyno to make money. Tuning is in the DETAILS and they do not have time to pay attention to the details.

The good thing out of this is that you learned how to tune your own car and I know that you now have a sense of satisfaction that is unrivaled. Now, there is no going back. Now, you will find yourself continuously tweaking that tune. Now, you will find yourself spending more time reading the ECUflash forum, the best forum on Evom. It is a great learning experience. That is what I went through.

You must have been really proud of your achievement when you destroyed that LS1. I can see the look on your face, your smile must have been ear to ear. Please tell me what your friend said? What was the look on his face?

Don't listen to DSG about the road dyno. Road dynos are really good when done right and the variables affecting the car are kept to a minimum. Treat them as a before and after tool and you will not go wrong.

Good job on the tune. You are a quick study
