Hello long time reader I guess was wondering if anyone has done the hondata cpr kit with the infinity 30-7108. I have the cpr kit spliced into the rywired tucked budget obd 1. obviously I’m going a dumb route but can ckp in obd2 can be wired to the stock harness or into the aem jumper harness since I’m not using distributor crank position. I would like more info on anyone running the aem with coil on plug as well.
If everyone scared or does anyone even run aem infinity oof ik it’s hard when you don’t get the part from pick and pull oof.
yes I have autism I have a 32in in the pass seat and touch screen display and a desktop wired up in the car ouch Honda gang maybe I’m not real I’ll delete my post in a week cus y’all weak oof
Forums are slow these days. There's not a ton of us left!
The CPR is pointless with the Infinity. It would actually make your life harder to try and repurpose it. Just run your four signal wires to the coils and provide coil power (BLK/YEL in the distributor) & ground to them.
The stock CKP and wheel sensor does not provide great resolution to us as a crank sensor - To be fair I've not tried myself but relied on the fact that many have, unsuccessfully. There are options out there to repurpose the location on the oil pump with a better sensor and a higher tooth count wheel.
The Infinity is a great piece of hardware. It's been around for yeaaarrss at this point and it's still top of the line for capability. Should be a fun project!
Yeah let me change my whole build real quick?? Does anyone have hands on input for the aem infinity I already have the cpr in so it’s staying oof. Yes it’s been around for a little for the infinity but where’s any info on it. Just need my sensors talking to the ecu
Ooof imagine not taking advice from someone more knowledgeable than you
Ooof imagine thinking you know better but can't be bother to do the basic research yourself
Ooof imagine talking **** to people you're asking for help
Fine, go ahead and spend whatever time needed to reverse engineer the CPR into your infinity and lose ecu capability in order to rethink your wiring. The CPR is an add-on hack to add features to an add-on hack to add features a stock 30-year old ecu. It not only serves no purpose with your Infinity but it just plain won't work. The only way that the CPR stays is if you stick with the S300 and that's stepping over dollars to pick up dimes.
HP Academy has a course on Infinity.
Evans Academy does too.
Tons of races use the Infinity.
It's the spec ecu for Trans Am cars.
I have a s300 p28 that’s why I did cpr and wired it and then found out the v3 doesn’t support cam trigger how I wanted it too. I have the cpr already wired in ik aem already has drivers. I have it wired to the factory loom with the adapter to go to aem ecu. Why or how should that not work with the aem? Wouldn’t it already be adapted oof
The AEM doesn't need any drivers, assuming you're still using OEM style coils as you have in your photo. It has ignition coil outputs. You can use only one of them if using a distributor or you use four of them for COP..
You need to bypass the CPR. There's no way to understand how you've integrated it into your loom without seeing pictures and a schematic, but it should be as easy as running the four coil output wires from the CPR connector straight to the appropriate coil output pins at the ECU. Then sell the CPR setup and get a little money back.
Despite my best judgement, I did your homework for you OP.
If you had the S300 and CPR working on your previous setup, bypassing it should be exactly as I described in my previous post. The coils will still get power and ground at the distributor and thermostat housing, respectively. All you need to do is remove the CPR unit and connect you four coil trigger wires (terminals 7-10 on the CPR plug) to the coil trigger outputs on the Infinity loom. Done and done, you don't have to rethink your entire build for it.
Do you understand what the CPR does? Did you look at the diagram I posted above? If you take a few minutes to do that, you won’t be confused.
Remove CPR.
Remove the four wires that are currently headed toward your ecu from the back of the ecu connectors.
Remove the four wires that are headed into the CPR connector from the engine side of the loom. The whole CPR is now deleted.
Connect those four wires to whatever pins AEM say to connect them to, assuming they are pinned out on your a-dapta-kit there, assuming it is pinned out for that. If it’s not, you’ll have to get creative.
Yeah I’m not going to cut into the harness anymore everything has 0 miles on it never ran. Hondata said cpr only works with hondata s300. I think I’m confused cus it’s more splitting open wires that Im not comfortable doin I Will save for custom harness since I’m still going to do ckp and obd1 obviously has it in the distributor so that’s another thing I would have to splice in. Obd1 seemed the way when i started. Guess I was doin the impossible thanks old man for responding.
I will add these 2 cents.
- Sell the retrofit kit - Keep your coils most of the wiring
- Run everything of the AEM as has been noted and diagramed for you above.
I have had mixed experiences with the oem pick up and always ended up with the AEM EPM or T1R HAll effect cam gear pick up .
- If you have issues with signal : AEM EPM ( if you find one ) or T1R HAll effect system and now honed development has a replacement for the now discontinued AEM EPM ( https://honeddevelopments.com/produc...ger-kit-basic/ ) . Or a nice Crank/Cam wheel setup, but havent used any of the pnp kits .
AEM infinity is a great ECU ! . you will enjoy all the benefits it brings.
I have the t1 cam trigger installed already but my harness is obd 1 would have to get an extension I believe to go into the little bundle by the ecu that doesn’t go to the obd1 harness
Aem Infinity
