Curious about a retune

[actiew]

Curious whether I need to re-tune my standalone??? Originally had my SR20 swap in a S14. S14 has been put to rest and now I am putting my entire swap into a S13. Everything engine wise is staying completely the same beside minor stuff to do that is diff for a S13 than a S14. So the question I ask is, do I need to re-tune my standalone if the ECU is tuned to the engine that is there being swapped???

What kinda of EMS are you using?
Im thinking yes,

I don't see why you would need a retune..I mean the tune is for all the engines sensors and timing/air fuel ratios..it doesn't control the chassis related stuff.i mean if you have a wideband gauge just watch it after the swap to be safe

I have an AEM series 1 Standalone with HUEGO, 5 bar map, proper CAS disc, etc... everything that was in my old set up that ran supreme on first crank never any issues.
@ angel mkiv (http://zilvia.net/f/member.php?u=90455) thats what I was thinking since its EVERYTHING from the old swap, didnt even change the speed sensors in the tranny, just got a dakota speedo module to read it correctly. Yes I do have a wideband gauge, and thats what I was saying but folks always want to retune... why fix it if it aint broke... but if Im wrong please correct me cause nothing worst than a bad tune in my book

I failed at comprehension, I thought you switched engine S14-13.
No need for a retune.

Yeah thats what I figured, but sometimes you need a second opinion or someone to concur to what you are thinking when someone is trying too convince you other wise.
@MADE no just chassis from S14 to S13, still same motor and setup up that the standalone was tuned to originally. No major changes, just different FMIC piping

Thanks for the help
