Well i blew up my 99 max a couple of nights ago, with 211k miles and spraying nitrous i knew it was going to happen sooner or later. So in searching for a new motor i found a friend parting out a 2000. and im curious to know if i could use the ecu (and transponder) from the 5th gen along with the motor so i dont need to use an safc. i was told the 99 cali spec (like mine) and the 2000 are more alike then the rest of the fourth gens because of the o2 sensor setup and egr. Should i stick with my computer? or should i just go ***** out and go 3.5

 

I say go 3.5 if you have the time and resources

 

 

Dek with all that is a quik swap... my 99 engine eas replaced with a 97 fed engine and when i bought the car been dealin with cel problems since... im goin dek simply for reliability and quikness... its almost direct drop in aside from injector clips...

 

I not as simple as swapping an ECU. The price of a Vafc II is so cheap now that its almost a no brainer. You would be doing so much more trying to make that ecu work let alone flawless and CEL free. Plus with the Vafc II you can set your activation point for the power valve verses using the default 5th gen cross over point.

 

Ecu swap is simple..grab the key and ignition and ecu and harness...make a step down harness swap engine and call it a day... no?

 

That's what I thought. Would the step down harness even be nessecary?

 

Op: how much nitrous we're you spraying?

 

50 dry. It didnt blow completely it just has 0a compression on cylinder 2

 

Step down would be necessary mainly cause they have diff plugs... ir at least thats what i remember.. maybe im wrong its been a while since ive looked lol.... ill be in the same boat soon bro... plus i trust dek over 3.5... thats just me tho

 

Why do you trust del over 3.5?
