That I'm not sure of 100%....but I was always told that there is no difference in the engine, etc... only tuning/emissions. If you asked MMLMM, Honda, IdahoRob, etc... they'd def. be able to tell you....

LBZ and LMM injectors are different. The LMM tips have 1 less hole in them. They could work but you will prolly have to do some tuning to get them to run smoothly.

I would look for LMM injectors if you are having this many problems. Also what do you mean the computer fried? Your ECM? or the GPCM? Your flow rates are stored in your GPCM on the LMM. I have a spare if you need it.

it was the ECM that fried, sumthin to do with the injector nozzles being clogged or to tight to open up and some how fried the computer from what i was told by the dealership, and they have checked everything, and it comes back as the injectors are bad, and they are supposedly brand new ones from DDP, or thats at least what DDP CHARGED ME FOR!!! Thanks but nah i shouldnt need the GPCM, if i did they would cover it under warranty for me, only if they could get me the injectors under warranty!!!!

nope not yet, dealing with the injector issue, DDP doesn't want to warranty the injectors cause the nozzles are clogged, but like i have been trying to tell these ppl, how are nozzles being clogged my fault when the truck hasnt even cranked up and ran yet!!! so i am lookin for stock injectors or hopefully they will warranty these, but idfk!!!
