Oh, ok. so the map is a whole seperate thing. This discussion is about replacing the stock wastegate solenoid for improved boost control.

 

Great info... something that would be great to have added to the Wiki!

 

Thanks for the congrats...baby owns all now lol, im sure your expenses are double lol.

 

I recently got a Tactrix cable (1.3u) and Evoscan/Ecuflash and have been reading many different post including Merlin's EcuFlash guide and posts like this one as I am very interested in being able to capture my L-C1 wideband (successfuly doing so via Evoscan) and just received an Omni 4-port sensor which I will be installing this weekend to log boost.

The current map installed on my ECU was tuned by a friend of mine unsing Access Tuner Race to be loaded via my Cobb Access port which controls a Perrin EBCS.

My question is, I have used EcuFlash to get the map into a bin/hex and have been familiarizing myself with the map in EcuFlash rather than the Accessport Tuner Race as I want to be able to log boost etc. Since I have a Perrin EBCS installed, being a noob to tuning and after having read many posts, I wonder if there is any way anyone can help guide me to the specific tables in the map within EcuFlash that I need to pay special attention to in order to ensure that the EBCS parameters properly ported into EcuFlash. I can even post the tables so that I can then get a more thorough examination from my fellow Evom forum.

I other words, in theory, now that I have the map in a hex/bin format, should I be able to burn that map as is into my ECU and suffer no consequences? I think the asnwer is no, that one should always ensure all the parameters are correct rather than chancing it and therefore why I am asking.

Any help is greatly appreciated.

 

Bump for some help...

 

There is some trial and error when tuning wastegate duty cycles. With the IR/Perrin solenoids, changing the duty cycle 1 or 2% can alter boost a whole psi. So make small changes while datalogging.

 

Thanks for the response, as I mentioned any help is grealy appreciated. I will definitely take head and make small incremental changes and log. I only wish I knew what specific tables to play special attention to with this Perrin EBCS. Better yet, should I ditch the Perri EBCS and map another way? I just ordered and received the Omni port 4 bar and was wondering if controlling boost with this is better?

 

The Omni 4 bar map sensor and the Perrin EBCS can be used together. If you modify your rom per mrfred's instructions, you can log boost via the map sensor. That is a necessity for tuning the EBCS. There is a thread with specific instructions on how to do direct ecu controlled boost, also by mrfred.

 

how does this valve compare to the MAC/AEM/TURBOSMART valves?
i have heard people complaining about the valves failing in both cases.
what according to you guys is the better option?

 

GM BCS.

This is the Same Solenoid I have in my car, Works pretty good but it doesn't control boost as well as the GM one from what I have heard. It came with my car so I didnt bother swapping it out

 

Thanks For the feedback guys.
Bless.

 

Correct me if I am wrong, but my understanding is that if it is a MAC valve based solenoid, then it is not as good as the GM or the Tactrix BCS. I have noticed that almost all of the MAC valve based solenoid are large, much larger than the GM and Tactrix. I take it that the Ingersoll Rand is MAC based?

 

The IR solenoid is made by IR I believe. It is similar in size to MAC but it is otherwise a different design.

 

But is the valve inside it a MAC valve. IIRC, the MAC valve based solenoid are not as reactive/fast as the GM and Tactrix.
