So I am putting my car back to stock, previously had turbo back, intake and mbc set to 21 psi. I have removed the mbc and intake and replaced the boost lines with brand new factory evo ix ones. The car now won't boost above 12psi (wastegate I presume).

My question is it due to the fact that the ecu was flashed by turbo trix? Or is it my actuator (the little controller under the intake). If you believe it's the map does anyone know where I can get a base map to re-flash it?

It's a 2003.

Thanks,

Are you sure you have the restrictor pill inline? When i re did my vaccume lines i was unaware of this pill and i couldnt boost past 12psi.. Just something to check out..

 

I am sure of it. I literally pulled the lines off of a brand new ix no more than 1,000 miles. The lines were marked and placed back in my car the exact same way.

 

Factory boost selonoid pluged in?

 

Plugged in yes. Maybe it's broke though? IDK just trying to eliminate issues.

 

You may have marked them, but you either didn't install them properly, or they are defective.

The red-tipped short hose should go to the wastegate nipple, and the other short hose should go to the turbo nipple. There should be a restrictor pill in the short hose going to the turbo nipple and one in the long hose coming off the BCS.

Btw, good on you for trying to figure it out. There have been countless used Evos bought where the owner said, "I bought my Evo used 6 months ago, then just this week I added a boost gauge and only see 11psi - why is it so low if it's stock?" Well, it's because douchebag previous owners put it back to stock after modding and ragging it out, and they had no clue how to re-install the stock boost system. It sounds like you went the extra mile trying to install the proper OEM lines in the proper configuration, but you didn't get it right, which is why you're seeing base wastegate pressure. Ensure the hoses are oriented how I mentioned above and that they have both pills. Don't rely on the fact that you took them off a IX and put them right back on your car...be sure to verify each thing I said.

 

Thank you for your input I fully understand what you are saying because I was that a$$hole that bought a used evo with 12psi. So I am rying to spare the next buyer from this. I know that I have the lines hooked up the way you mentioned red tube to the actuator and all. But I will review this again. And can I physically see the pills? Are they inside the lines?

Also where can I get a base ecu map anyways so it's not running as rich?

Thanks for the input and help.

Yes, you can see them AND feel them - yes they are inside the hoses near the ends.

You mean a stock 03 map? You would need to first borrow a Tactrix cable, download your current ROM, send it to someone like Dynoflash, he will put it back to stock, email it back, then you upload it and are done. Or, you can drive to him in CT to get it done in person quickly. Who are you currently tuned by? Whoever it is should be able to flash you back to stock no charge.

 

Yes I am referring to a stock 03 map. I believe the car was tuned by Turbo Trix. I bought the car without any mods but it was flashed for the mods it did have intake and mbc. Once I got it I put an intake back in and fixed the 12psi issue with my MBC. At this rate I don't think it's worth finding out who tuned it, but rather just finding a stock 03 map that someone may have saved.

I have a tactrix cable and are familiar with the ecuflash software. I can clearly see the AFR's and timing are modified from what a stock map would look like. There has to be someone who has one saved on there computer...

Now that I am thinking about it doesn't the ecuflash software have a somewhat stock base flash as a default?

 

You can't just use someone else's stock map. You need to have your map put back to stock. No, EcuFlash doesn't have a default base flash. You can't just use anyone else's ROM - you can only use yours, because it has to have the right firmware and the right immobilizer code. Don't try to cut corners - yes, you can change the immobilizer code on another ROM, but you still have to make sure it's matches your 03 firmware. It's best to take your own ROM and put it back to stock.

 

IT WORKS!!!

I had to put my intercooler pipes back on (they blew off last night when I was trying to test the boost). After 3 or 4 pulls the car finally went to the proper 18-19psi. I guess the pills or whatever were jammed. Either way it's working now.

Thanks for all of the help guys.

 

and my evo got a new mod from your visit to the shop

 

^ You're welcome now you can do my springs and put back the stock sway bars.

As for why it's fixed....

The night before after putting the intake back to stock I went to do a WOT run to test the boost and instantly LICP blew off (stupid me didn't tighten it enough) So I unplugged the MAF and drove back to the shop left it for the next day.

Following day I re-tightened all of the clamps and reviewed the lines. I just made sure that I had them in the right spots (long hose on the first nipple of the solenoid to the actuator -- red tipped hoes -- then the other portion T'd off to the turbo. The smaller line was on the second nipple of the solenoid and it went to the intake box.

Took it out of the shop and did 2-3 WOT runs boost was stuck at 12psi DARN!. Next run I made it spiked to 25psi and I said ****. After that it stayed at the normal boost levels 18-19psi.

So I guess there was no real method to my madness or why it worked. Just double check your work and triple check to make 100% sure you have everything right.

Thanks again for all the help.
