mechanicatheart Posted June 25, 2013 Posted June 25, 2013 so I found out today that the car I'm buying has a new chipped p28 ecu. Any info on it regarding common problems with it? Any and all info would be appreciated
Xeryon Posted June 25, 2013 Posted June 25, 2013 On a Honda that isn't a race car a 'chipped' ECU is a pointless modification. It allows you to modify fuel cutout and vtec engagement timing, among other things. All of which shouldn't be messed with unless you have performed substantial modification to the cars engine resulting in considerably more power being produced (I.E. turbo or fully machined N/A build) Anything else you could possibly bolt onto the car: exhaust, intake etc will not cause a need for the ECU to be reprogrammed.
mechanicatheart Posted June 25, 2013 Author Posted June 25, 2013 the car has a boosted b20b in it. as far as ik right now it still has stock internals so its a low boost car right now till I have the time and money to upgrade
James Matteu Posted June 25, 2013 Posted June 25, 2013 How do you know it is low boost? I think you're guessing based on it being stock internals, otherwise you would've volunteered that info without being asked.
mechanicatheart Posted June 25, 2013 Author Posted June 25, 2013 sorry I was just trying to get more info about the ecu on a general aspect. like what can and cant be adjusted. I was told the bypass valve spring was set to 8lbs
Xeryon Posted June 26, 2013 Posted June 26, 2013 Well, in that case you would want a chipped ECU so that the car could be properly tuned. Next check is to find out if previous owner has had the car professionally tuned or was just winging it.
mechanicatheart Posted June 26, 2013 Author Posted June 26, 2013 from my understanding its hasn't been modified yet. I definitely have plans to take the car in and get it tuned. would just a baseline tune suffice for now? nothing has been upgraded at this point to support the turbo
Xeryon Posted June 27, 2013 Posted June 27, 2013 Sure base is probably fine. I wouldn't go balls to the wall racing but you aren't likely to kill anything that wouldn't have blown up anyway. A lot of people never get their car tuned after a turbo. Not saying it is the right thing to do, just noting that it is what a lot of people do.
mechanicatheart Posted June 27, 2013 Author Posted June 27, 2013 I have plans to get it tuned soon before I drive it too much. I'm taking it to Knoxville Performance to help me get it running right and tuned hopefully within a week or two
cranny Posted September 12, 2013 Posted September 12, 2013 Chipped ecu's typically are tuned with Crome. Crome is garbage. Junk. And should not be used by anyone in my opinion. You want a boosted Honda , buy a hondata S300. Do it right. People that put thousands into their cars and than cheap out on the most important part of the puzzle baffle me. Running you multi 1000's investment with a 25cent chip from radio shack is not the way to roll.
