this is kinda a shot it the dark but i need help. i did a mini me swap with a d15 block with a d16y8 head. i have the new ecu to run the vtech. now my problem comes in with the new ecu i have try like 10 base map and none of them run right. i was told and read that is is a p28 base map and it sould run like a dream with vtech. with all the base maps the is a massive fuel and air dump and the rpm will not exceed 4000. the stock ecu runs fine but no ecu no vtech. i have a push button vtech hooked up and i works . i just want the ecu to run like it should. i have checked my wiring 5 times and no fuses are poped. i have tryed a 2nd p28 ecu samething happens. i am using chome to burn the chip. idk what the hell is going on has any been here b4 with a mini me swap. i just need some help

 

did you remove the oil jet? in the block
also do you have any cel's???? if so vtec will not kick in

 

You need to calibrate the ECU for a 1500 cc engine not a 1600. Changing the head does not change the displacement of the engine. A stock P28 assumes the engine is 1600 and will give it too much fuel.

 

Nah that's not it, he's in limp mode for some reason.


Got a CEL?

 

yeah thats not it, 1.5 and 1.6 have the same basemap, i ran a p28 on my d15z1 without any problems and got 46 mpg.

 

you i pull the oil jet pulg and i did a push button vtech and the vtech hits but the ecu just wont hit idk what is up. like it runs soooo rich and bogs and wont rev past 3 or 4 grand. i can try the cc thing but the p28 base map should be plug and play

 

i was told it my be the distributor cuz the d15 one that i have was after market and it fit the head and it runs grate with the stock ecu

 

Which button do you press? 1-9? Or do you press pound?

 

i think you have a friend or something giving you bad info..
its vtec not vtech, vtech is a name of a phone, also the d15 non vtec dizzy will not match bolt holes up to a 1.6 vtec head.
now if you have a cel on the ecu will not engage vtec so do you have a cel on?

 

Trust and 94chb have the right idea. Here's your problem: a car ECU isn't made to run a phone. If you pushed buttons on the phone to retrieve a CEL, you probably gave it a CEL instead. That will definitely make it run "grate" and could lead to the problems you are experiencing.
