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!

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.

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.
