Hi everyone,

After going back n forth on the topic if adding power to RL in this thread here:
https://acurazine.com/forums/showthr...7#post13120477

I talked to Todd to discuss if he'd be down for some research with me. I come from preludes and S2000s and RL is a new world for me. I am trying to do some research on fuel management and engine on RL.

I am going to need a lot of help from people on here who has some A/F charts/dyno results from their mods and all.

For example, 06 S2000 runs super lean if you just add TP to it. Once you do a datalog of your runs WOT after just a TP, AF is through the roof and if you don't fix it, you will have to say goodbye to your engine.

I am looking similar kind of info on RL. Has anyone removed CATs and did a dyno run to see what happened to their A/F ratios? Has anyone put I/H/E and did dyno runs?

I saw someone did install a 3.2CL supercharger on RL. Does anyone know what happened to him? How long did it last? Was it reliable? Any insight or info would be helpful.

Like I said, it's a start and it's going to take a while. All I am looking for is input/help from people who have done anything like this and can chip in. I am not doing this project just for myself but for anyone out there who is interested to learn. If nothing else, it will be a good research project?
Let's start, shall we?

Thank you in advance for keeping the thread on topic and clean.

Here's Bob's Dyno after 3.5L TL AEM CAI and 5zigen Fireball Mega exhaust. I am not sure if the bottom lines are stock or not.


There are problems with trying to Dyno the RL. #1 is finding AWD Dynos that perform the same. #2 is there is a pretty solid consensus that the SH-AWD holds back power b/c it thinks the wheels are slipping. The alternative is to disengage the drive shaft and force the power to the front wheels. This is what was done on an RDX first (I believe) and was repeated for the S/C experiment. The only result of this is that no two Dynos can be directly comparable unless they are done on the same model equipment. As long as that is constant, the measurements can be compared.

BTW, it was a TL S/C they used.

Here is the link of Bob's endless search for true RL performance. There are even some mentions of A/F ratios.

Also there are no headers for this car. exhaust manifold is in the block, only thing you can do is delete the pre cats with Richie's or similar pre cat deletes. I plan on doing high flow ones eventually and possibly a jpipe. But that would be the extent of what I do as shit on this car isnt cheap to fix.

Looking foward to seeing what you find about this car. My guess is its the same animal as the 3rd gen TLS just with SHAWD

You saw this thread. Look for user ctgasman

Thanks L's TL for the info. I have worked with Todd on designing/modifying header for my cars before and I think if I can get enough time for him, we can look into that part as well.

Honda makes their headers in a way that it's very restricting and the flow is not easy. Although that's not where you gain power from what I've seen so far. You make power by removing those CATs. We have tested S2000s with I/H/E with no gains until you put a TP on it. So the culprit is all the CATs and stuff before you get to exhaust. I am going on vacation next weekend and will be back after 2 weeks...that's when I really will do more research, till then I am just collecting all the information I can.

Chas2, Yes, I read through all that and I don't think I found anything that would really help learning the fuel management or engine. All it talks about is how they fit the supercharger, not necessarily what was the research involved. Maybe I missed that part in that thread?

I am tempted to bump Bob's thread and ask all those guys who were going to dyno or bump the supercharger thread and ask the guy how is he doing now and how is the car running after so many years, you know?

No problem and yea Hondas really wake up when you delete the cats. When i did a Test pipe on my 2nd gen TL with Supercharger she screamed. It was very fast. When i deleted the cats on my 09 Accord Coupe V6 6MT even with stock cat back it made almost 290 on the dyno and ran low 13s on stock rubber.

Any stock honda motor can take up to 5psi boost with out doing any timing adjustments. The RL is fine with the supercharger but if you want more boost then you will need a standalone ECU to change fuel and timing. I am going to put twin turbo on my white RL next year. I'm just going to run 10psi but that will wake this car right up!

Chas2

I agree, everything is anecdotal from ctgasman. You should try to contact him and see if he ever went to 6lbs from 2.5 lbs and what happened. If he got 45 more whp from 2.5 lbs, maybe something a little less than 6 lbs would have worked...and still been within the realm of mapping.

The RDX Project on vtec.net showed that they could increase boost to a certain point, then the fuel got a little to lean, so they backed it down. I realize that is a turbo, but I think the same principles apply, at some point the ECU can no longer compensate and there is not enough fuel for the air mass.

You can always use the AEM Fuel/ignition controller its a decent piggyback

Works with latest OBD-II race vehicles including those with variable valve timing
Variable valve timing controller based on engine RPM and load
Injector inputs with simulated injector load used when remapping OEM injectors
Injector controller for either remapping of ECU output (+/- 100% trim) or as a stand alone extra injector driver
21x17 maps with configurable load and RPM breakpoints
Analog in/out for remapping/clamping MAF
F/IC can draw power from PC USB for quick and easy calibration changes - even when it's out of the car!
On board 64K datalogger
Drives high or low-impedance injectors with use of Peak & Hold Injector Driver Box

LSM legend wow thats great you just copied that of their page...
Did you even read to see if they have a part # FOR RL? They dont but im sure they have to have one that will plug in and i will work my tuning magic on it from there.

Carbon Legend

No they do not have a part number for the RL. They do not have

AEM Part # 30-1911 for honda and acura with Mag Pickup (Hall Sensor)

AEM Part # 30-1910 is Universal 4/6 Cylinder

AEM Part #30-2985, 30-2986, 30-2986C are possible Extension Harness
