so i have some questions about going turbo. if u run a stock ecu at 8psi what is the chance id blow something and is there a base map i can get for it on my stock ecu?

 

I say you really have a good chance. Its just a matter of time before your engine will blown. Dont boost if you dont have a good engine management system.

 

LOL fail! search there is a million+1 threads if u cant afford fuel management then dont go boost period

 

^^^ I must say I have to agree with this kid.

 

I had the same question awhile back, the search button does amazing things.

 

You will blow the engine on stock ecu

 

I've got tons of maps for the stock ECU. One of Europe, one of the U.S., one of South America... oh wait, nobody has cracked the ECU yet!

Search.... besides boosting on a budget = headache and more $$$

 

oh wow i didnt know people actually asked this and i though i was a noob lol. i think this is the way to best discribe it IF YOU DONT HAVE CASH DONT BOOST lol

 

not to be a douche but..if you search you will probably find like said above hundreds of threads because no one searches and posts this same question pretty much every day. DON'T BOOST ON BUDGET!

 

wow i didnt know that many people are _______s. it was just a question and i didnt say i didnt have the cash. thanks anyways

 

Relax. There's no reason to not atleast do a base tune, you can get an F/IC for a few hundred bucks.

 

Calling people _______s won't get anyone to help you. If you weren't so ignorant and searched you would have found dozens of threads about this topic. Do yourself a favor and research this forum you will find a whole lot of useful information.

 

i have done research but i know a couple of people run like 5psi and no managment and they were fine. thats why i was asking. and i have a greddy e-managment so im fine there to

 

Incorrect, never safe to run without management. Let me put it this way, I ran my car at 5psi WITH management without the complete fine tuning; it came with a preloaded map & my car ran MUCH better after fine tuning. Trust me, makes a world of difference.

If you intend on running 5psi without management.....I'll be here waiting for the "my motor blew up cuz I went turbo without any management" thread; it's inevitable.

 

There is one turbo kit that runs with no management and that's the ill-fated ZPI stage 0. However, the consensus seems to be to get an intercooler and some management and *then* it's a great light boost kit. If you do this with any other compressor, you're rolling the dice, especially if you have no gauges to monitor the vitals in real time.

As for your original question:the stock ECU can't be reflashed, Toyota has it locked down. The only way to get around this is with a piggyback which I see you have.

 

Just for poops and giggles Ill be running 7psi 440cc injectors and Walbro fuel pump on Stock ECU with a T3/O4E 50 Trim!!!!!!! But it wont be for a while I ran into some other issues outside my expensive obsession with cars. I ran the same T3/O4E 50 Trim turbo before at 6 psi with NO injectors and NO tuning at all for almost 10K miles no issues. I guess it depends on ALOT of things. NO TUNE is not reccomended.

 

Why dont you just get a FIC so the damn thing works right?

 

^thats what I reccomended, it's only a few hundred bucks, it's stupid to compromise your motor over that.

 

Just cuz its fun, easy, and people get really mad if you do it lol.

You saw my other build that was cancled before dawg

 

well i ran 1.5yrs on a stock ecu on a zpi stage 1 with 440 no problems but i wont recommend it. just save up and do it right. the first time or if u have money to blow buying motor and time to waste putting it in be my guess. it never good to half ___ something
