i think i over boosted and threw a code because of it I set it yesterday in 98 degree teps. Its 69 and rainy here . I had it set for a peak of 25 psi in 98 weather it got cooler and the air got more dese and i threw a P1235
Fuel Pump Control Out Of Range code. the CEL came on then when out of gear it would idle a 2k. i shut it of and restarted it and the thing idle fine. I turned boost down a max of 23psinow. anything ever happen to anyone?

That happened to me, once I got the MBC in my car. I took it off immediately, and got a tune at Road Race Engineering using Ecutek. So far so good. Get it tuned, Ecutek can raise your boost threshold.

 

i've had that code too, its from the ecu not liking the boost levels. this ecu is too smart for its own good

 

Would this code be thrown If mbc and Ecutek was installed?

 

You don't really need MBC if you use Ecutek. You could use MBC, but I prefer to increase my boost using Ecutek only. And Ecutek can alter the boost threshold map so that it doesn't throw CEL and go into limp mode.

 

The tune can be adjusted to account for an mbc if the tuner understands how the tables work. However, you still have to make sure you keep your boost level adjusted properly.

For the most part, there is no need for an mbc when the ecu is tuned using EcuTek tools.

 

1235 due to partial throttle overboost.

Hated it, got EcuTeK, went away.

 

y r people running mbc's with ecutek tunes, when ecutek controls boost?

 

My theory is that it's takes less time to tune it using MBC instead of altering the boost maps. SHORTCUT

 

I would say that is a fair assessment. We had a customer that drove up from florida because the only EcuTek tuner closer to him said he would not tune the car without an mbc. No idea who that shop was and I don't think they are on here.

 

Hey guys, thank you for the advice. Im just waiting on my greddy tic to come in before I get it tuned. I figured the MBC would be a great band-aid for a little more power until it was tuned.
Sorry for the broken english in the above post. I was in half in the bag when i posted it.

 

P1235 code also came up when I adjusted the stock wastegate. Idles at 2k. I will mess around with it this afternoon maybe set my wastegate back to stock. I really wish these parts ordered would come in so I can get an tune.

 

1235 SUCKS!!!! I get it from partial throttle boosting

 

Ecutek can raise the threshold. No more codes for me after I got it tuned.

 

MBC = FTL. Either get the ECU to do it or get a EBC. I dont care what anyone says, a MBC is a ticking bomb waiting to happen if you are not watching your engine parameters i.e. AFR and the such. Feel lucky the ECU caught it and limp you up some. Theres a reason for the code, not just to make you mad.
