1.8 -vs- 2.5 ECU on a KL-ZE

[KNOCKOUT]

From which model (MX-6, Probe, etc) 2.5 ECU should I use with the KL-ZE and is it a direct "plug-n-play"? Meaning, is it a direct swap in that the same wiring harness connection is used from the current 1.8ecu to the 2.5ecu?<P>I should be ready to finally attempt to start my MX-3 w/KL-ZE installed by early next week....still waiting for the MS8 manifold to arrive.

hey man, here is a question for you,<BR>how does a 2.5 ECU look like, cause I asked a guy from a junk yard to get it for me, and it looks too small, do u have a picture of it by any chance?<BR>thanks

Actually, yes, it is small. All it is is just an integrated circuit board with a cover over it to protect it.<P>I haven't actually physically looked at mine but it should be somewhere behind your glove compartment. Sorry, no pics though.

use the 2.5 for sure I hear the 94 probe ECU is better something about the air temp thing being different<BR>but if you can aford it send it to corksport and get it reprogramed for the ZE<P>Yes its "plug-n-play" you just have to transfer a relay over you will see what I'm talking about when you look at it<P>Size is 7" by 7" by 1"1/2 thick silver box with the plug on one side thats bright greenieyellow<P>its located between the driver and passangers feet

I swapped in (and out) a '94 PGT ECU after my ZE swap. I bought the '94 ECU specifically because I already had the VAF from a '94PGT. I heard that the '94 had larger injectors, so I went with that. I really didn't notice any significant differences between the 1.8 and 2.5 ECU's. It did seem like the VRIS points were more subtle with the 1.8, but I didn't get a chance to dyno the car with each computer in there.<P>As far as installation, the 2.5 box will plug right in. There were difference mounting brackets on the one I bought, but I just swapped the brackets from the 1.8 box.<P>Hope this helps. <P> <BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by KNOCKOUT:<BR><STRONG>From which model (MX-6, Probe, etc) 2.5 ECU should I use with the KL-ZE and is it a direct "plug-n-play"?

KL is the block code for the 2.5L. If it says K8 that's 1.8L, or KF for the 2.0L.
