I have a semi built gsr motor going into my car this weekend and I was just wondering if a stock ls ecu would be ok to break in the motor with. The setup is

stock gsr rods
CTR pistons with a slight spacer in the headgasket to lower compression a bit

ported and polished head
supertech valve springs and retainers
itr valves
skunk2 pro1's

I plan to get the car tuned with RC 310's and a walbro 255 fuel pump but just to do the initial break in would a stock ls ecu be safe with stock injectors/fuel pump?

 

NO! Tow it to your tuner.

 

No. If you ecu is chipped order a chip burned for your specific setup by phearable.net. He only charges like $30 and you tell him all your mods.

 

You can start the car with it, but as far as driving it around, I wouldnt do that.

 

 

Thanks for the input guys! Guess I'll be towing it lol.

 

"question about breaking in BUILT motor on STOCK ecu"

 

but ls ecu can maybe???????

 

Hey man, I'm new to this. Don't know if you don't ask, right?

 

Dont know if ya dont search is more like it. Judging by your sig, about being a drag racer; "crashing gears and banging ho's" and what-not, I didnt think you were "new to this".

A little common sense goes a long way in engine building, thats why I highlighted what I did from your question.

 

This is my first engine build. I had a turbo single cam before but it was a stock motor that was tuned on an SAFC, then a phaerable chip. Might be a dumb question to you but I just wanted ask and make sure. And since you're so observant, my sig isn't words from my mouth. If you read all of it, GHOSTWORKS/Mr. Parks said that quote, I just thought it was funny.

 

I did read the entire thing. How was I to know that quote was attributed to "GHOSTWORKS"? Because the word "GHOSTWORKS" is written beneath it? You know you can "quote" someone , like this right?

Works much better that way. GL on your build.

 

Thanks for finally contributing something positive to the thread.

 

I dont see any reason why the stock ecu will effect the break in period. As long as you run a wide band and ensure that the static timing is not largely advanced, you should not run into an issue. Come on people, he is talking about seating the rings, not racing around at 9k.

The problem i have with towing a car in is that if you have something you forgot or missed it could cost alot more. Just use the ecu for break-in and than get it tuned properly. Even a pherable chip is not that accurate, especilly with timing needing to be precise.

Good luck

 

Except his stock ecu is for an LS and his motor is a gsr, and ctr piston, and pro1's, and rc310......your right.
Phearable LS CHiP's not that accurate as Honda LS. I would reconsider and use stock LS ecu.
Now that I re-read, why the hell would people suggest a tow?!
What a waste! Check timing and break it in ya puss!

 

Yea, bigger injectors, late intake valve closing, more overlap, more compression, sure, stock ECU is fine. Its not like the most important aspect of ring seal is the first 3 or 4 heat cycles anyway, right?

 

So towing it to someone that will have the motor running on a map that correctly supports the motor is waste? Your post is a waste and we his motor doesnt last very long because he took your advice his motor will be a waste. I can't believe the advice people are giving to people now a days.

 

dont know why but i just imagined some pissed off little Scottish dude saying this lol. I used to think that CC was a bit on the harsh side when i started here but after seeing repeat and repeat of the same dumb question now i think if anything his words are TOO kind.

Honda-tech is like a senile old man who has lived his life working on Hondas. Sometimes the information he gives is ****ing bizarre and doesn't make sense, but sometimes it is worth more than gold.

READ!!! DONT ASK UNLESS YOU HAVE TO!!!

 

Fink maybe you meant to quote this guy, since thats who I was refering to-


You totally misunderstood my sarcasm, forgot you cant tell that through typing. My bad.

 

I guess some people don't get sarcasm...

 

As long as timing and air/fuel are within range the motor will seat the rings with no negative impact. The greatest thing about hondatech is that people ask for advise and all the *** munchers go crazy calling people stupid and dumb. I want someone to give me one proven negative outcome from breaking in a motor on a stock ls ecu, when the timing and fuel are on.

There is no need for you ******** calling everyone names for asking questions. I have seen many engines broken in this way and have had no problems. For many people towing a car to a shop to have tuned and ran and broken in is not practical. No matter what, i would never want to have someone else be the first to start and run a setup that i have worked long and hard to put together.

 

There wouldnt be a negative outcome if the timing/fuel are on. However, they wont be. See all the reasons I listed above.


I am italian though.

 

exactly....you'd think that would have been obvious to everyone.
