i just bought an LsVtec and its all rebuild with mostly all oem Parts and a few aftermarket parts. the problem is that First of all Vtec wont engage and i can beat my new car with my old Ls and i wanna know the right way to break a motor in? and why is my car so dam weak?

thanks for the help

 

what ECU? has it been tuned directly after the rebuild?

 

hook up vtec and get it tuned!

Agreed, what ecu are you using OP? stock ecu's dont cooperate well with ls-vtec setups. It's best to go with a chipped ecu, preferably a p28 or have your current ecu tuned with a standalone system like Hondata s200/s300.

 

To break it in, just drive normal, dont beat the crap outta it for the first few hundred miles

 

 

it has a P2t Ecu and its spitting out a crap load of CEL's so i ordered a P28 and a jumper harness from OBD2b to OBD1 and i hope that will help

 

I have been babying it but a few times i took it to about 6800 and that was to check Vtec i hope the ECU will fix it but the oil level is good and every sensor is hooked up and it has a bunch of codes for sensors that the new Engine doesn't have, because its a 99 Ex with a B16a2 head with a B18a1 block and the idle sucks so bad when its not warmed up and if you hit the throttle it dies wich is kinda crappy.

 

search... check out what codes. fix problems. vtech isn't working? do you have 2 sensors on it or 1? if only 1 u may need the second. get that working. Get to work. and along with proper working ecu.

 

dunno bout the warm up issue.

Damn dude I would not even turn that car up again until you get that p28, you should really read up and do some more research, your lucky you havent blown that sucker up. Make sure the p28 is chipped with atleast a b16 map and get it tuned in a hurry right after. ASAP.

 

search for sale **** on HT. get a hondata with s200! good buys avail. nm u juss bought that missed it.

 

what do you mean blow that **** up why would it with a P2T i had shops check it out they said i need a new comp but this one wont do damage just make the car run like a simgle cam

 

and oh isnt it bad to tune any engine that hasn't been broken in yet?

 

I would tune that sucker before i even fired it up man. You can do damage within the first 30 seconds without proper tune N/A or Boost.

 

doode just drive it...dont slam gears yet til about roughly 4k miles you've driven it

 

You have purple lights. Ls/vtec wont run well on anything. You have to tune it unless you like going slow

 

What kind of chip should i get for the P28?

Check oil pressure for the vtech maybe? Is the oil full? And you don't necessarilly need to drive the car 4k miles to break it in. You can sit there with it in neutral revving it a certain way to break it in. I'm not sure of the exact way but at my shop, when we get motors back from the machine shop, a quick 30 minute session of revving it and holding it to certain rpms for a certan duration of time is what we do. I can find out and you can try it.

 

well i got 99 si with a ls/v and im using the stock ECU(p2t obd II) plus an apexi neo controller and my car its running great! never hade problems!!

 

well i have the P2t but in a few days my P28 comes in the oil pressure is good and all the wires seem to be hooked up right but the vtec doesnt kick and most of machanic's and a few freinds have told me the new ECU will make a differnce.

 

you need a tune for YOUR engine

 

where is a good place to tune a car in Washington?

no, take it to the strip to break it in, or on the dyno, do some healthy pulls, just make sure its warmed up,

babying it is a myth
