Will a 95 ls400 ecu fit my 96 ls400? Thanks

 

No

1995 uses Toyota p/n

89661-50220 or
89661-50221 or
89661-50223

NOTE: original California cars for 1995 use different numbers than these, so be careful that you know where your car was delivered when new.


your 1996 needs Toyota p/n:

89661-50302 or
89661-50303 or
89661-50304

and higher number are preferred, due to newer programming which eliminated stalling after high speed operation issue

my 96 uses 89661-50303 with new capacitors and is working very well.

 

actually, they are interchangeable (ie will plug in and work) but aren't worth it as the '95 had a large recall due to an issue with stalling after prolonged highway driving.

 

Damn, I need a new ECU.... Mine was never replaced. Ugh.... I wonder if the recall is still in place?

 

I don't think the recall gets your ECU replaced, but it should definitely get it reflashed with the latest programming, which was really the only change.

 

Ok, I will call and get some info. Do you think I should replace all of the caps and then get it re-flashed?

 

it doesn't matter which order you do it, they won't be opening the ECU to reflash it, so they won't know if it has ever been worked on.

 

recall expired many years ago.

 

lil tip i switched mine to from fed to cali emision and besides the dead cats no problems at all and throttle shock eliminated

 

Thanks for clarifying, I had someone ask me the same question and I didn't know what to tell them, since I had some parts for sale.
