wat up tr this the deal..... i recently did a swap in my eg hatch and for some reason it wont let m go past 4200 rpm in any gear....(sometimes after the car is warmed up itll go past 4200 like normal)..... i have a p28 chipped for a diff. motor...would it be a ecu problem??? also while i was droppin it in.. the chain for the engine hoist accidently chipped off a peice of plastic of the speed sensor on the tranny and bent the teeth....i bent them back str8 and plugss up alright to the harness.... would it be the sensor thats bad?? before i buy one i was thinkin bout throwin ma boys sensor in to see if it makes a diff. cuz dem bitches aint cheap... last thing my speedometer isnt workin at all lol prob the sensor ???? please reply to me with any info on this

well i know the vtec wont work if the vss is broken. and if the vtec engagement point has been set lower then that could be the problem bc the ecu isnt reading the sensor, it wont let it rev past the engagement point bc it will harm the motor.

5500.....so im gueesin it wont let it go past 2step...thanks for the info

if ur mph gauge isnt working and it was before most likely ur vss is bad and vtec wont engage if that doesnt work! try wiring up ur 2step to a switch and turnin it off and see if it still doesnt go past 4200, thats the only thing i can see the reason of it not going past 4200, it couldve been chipped wrong.. any cel's???

yea it was working b4 so it probaly is bad...and i dont think it waas chipped wrong it was chipped for a diff. swap and i havent gott it taken to get chipped for this motor... the only check engine light im throwin is my IAT sensor and that cause whoever had it b4 me took out the sensor of the manifold and jbwelded it... no cel for vss

well if u dont have a cel for vss try getting the right maps for the ecu to run that motor, but still wire up the 2step to a switch and turn it off cuz that happened to a homeboy of mine, his 2step was set at 3k and it would rev past 3k and took it back to the chipper and got it fixed soo u never know! im not sure how to wire the 2step up to a switch but i know its possible
