The shift points and grade control in the ECU aren't that bad really, it's the mechanical shortcomings of the transmissions that cause the lack luster performance. That and the gearing.
The Hitachi distributors from the US A1 models use an internal coil as well. The only other difference I can think of is that the JDM F23A1 didn't use a separate crank sensor, right?
Solder the chip in place of the original one and your mileage info will be transferred to the new (older) cluster
Not much to it really, hit me up if you have any questions though.
Sorry for the delay, I completely forgot about this.
Here is what I did to transfer the odometer info from my original cluster to the new one
Once you have the cluster apart locate the eprom chip on the PCB that contains the info. On the 99 cluster it's to the left of the LCD read out. I...
No it won't mess with the immobilizer. The mileage and trip data are stored on a little pdip-8 eeprom chip on the cluster PCB. You can swap that chip to your new cluster to keep the mileage info with the car. I'll post some pics in a bit
Yeah I just saw that but I'll be damned if I can figure out how to edit my post to fix them. Here is the shared album with the pics in it, hopefully that works https://photos.app.goo.gl/sZQzascCZ1oEmBC67
lol it doesn't happen often on forums anymore.
Yep, need a 99 or 98 cluster and run a wire from the thermo sensor directly to the cluster. You can add the thermo sensor if your head doesn't have it, I made a post on how I wired mine up for my H23A swap here
For an H23A? It comes with a TEC TD-94U stock and from what I've found on different forums a TD-73U (99-00 Civic EX, DX or CX) will bolt up and work in it's place.
If you are going OBD1 a TD-61U from a 92-96 Prelude SI VTEC will work
Since I'm swapping a H23A into my 02' SE and planned on keeping power steering I had to have a new PS line built for it. I actually got a PS pump from H22A7 with the bracket and line end still attached (hose was cut off by the importer) on FB marketplace for cheap. So I took the fitting that...
Hey Serga, would you happen to have the complete 6th gen SiR service manual? I have a scan of the ECU pin out in Russian for the PCF and PCB but need some more info from that manual.
If that's what you have now and are trying to replace, yep. The mounting pins on the cluster are different for the 98-99 compared to the 00-02.
This is a 99
This is an 02
