[One_Love]

sorry for my newb question but i have a redtop and need a 62 but will a 63 work aswell.

[ILikeMy240sx]

yes.. same thing. I had a #62 ECU in mine (5spd ECU) then switched over to #63 because I sent #63 to Enthalpy for tune so now Im running #63

I thought the 63 was a Auto ECU.

[One_Love]

it dont matter anymore, i just picked up a 62 ECU.

[ILikeMy240sx]

Auto 5spd ECU all the same.

[Blown240sx]

wont the 63 throw a check engine light?

[nzmoman]

not if it's reading neutral...but I dont know how to do that.

i've been running the #63 for a while now in my 5-speed redtop. works great, a/f ratios look good, no knocking, and power is on par with similar cars with #62 ECU's, so i see no difference. don't try using an E5, though. it will run pig rich and you'll lose about 30whp. i have a dyno sheet that says so.
