I'm planning on getting a Cobb AP but I just purchased a Works Drop in and I would like to keep it in while tuning the car to Cobb Stage 1. I know that Works already makes the car run more lean and gives HP, combined with Cobb Stage 1 which also makes the car run more lean - is this too much and dangerous? I plan on getting a Wideband to monitor my AFRs but at the moment I don't have one and will be getting one as soon as possible after the Cobb AP.

What map should I use if I use a Works drop in with everything else stock?

Thanks!

No one knows? :(

How about running the stg1 HKSPF map?

I think this is my only option, though works has higher gains from the PF than HKS so I was thinking it might still be a fair bit off : /. I hope I don't have to just buy an HKS just so I can use the AP without big worries :(.

You will be just fine running the HKSPF map, the difference between the panel filters that are available will be negligible on an otherwise stock car. Cobb's OTS maps are very conservative to keep things safe with car variances. Load it up and test it out, then run the stock Stg1 map, doubtful you'll feel a difference, and still be running rich all way.

regardless, since you don't have a wideband I would do some logs with the AP to ensure everything is "ok".

My AP is on the way and I have a Works filter. I want to keep it, but went ahead and ordered the HKS to play it safe. I know the maps are rich, but without a wideband, I figured why not for $45. Let me know how it goes with the Works filter, because I'd like to run it too because it makes more power than other filters.

Doubtfull he'll feel a difference between what? I was assuming I'd feel a huge gain from just a stage 1+hks flash, won't I?

oh you will certainly feel a difference over stage 1 over stock no doubt about that at all.....I know I sure as hell did. I think he was referring to the fact that Cobb doesn't have a works map and to use the hks one.

Ok, good! But right now I'm running a MBC set to 22psi tapering to 17-18psi on the stock tune. I'm going back to ECU controlled boost, and flashing the stage 1+hks map. Considering I've been holding more boost than stock, should I still feel a nice gain over my current setup?

Yes I would think so...although its hard to tell based on the MBC you have had. I still think you will see some nice gains though for sure. Lose the stock cat and exhaust and enjoy stage 2 though as soon as you can.

^^^ That's the plan! I aready have a catback, and once I get a test pipe or HFC I will switch to Stage 2.

If the OP and I decided to run the Works filter with the HKS map (without widebands), how could we tell it was "safe"? If LTFT's and KR at WOT were in spec, would that be a decent indication?

I searched across both Evo forums and couldn't find anyone running the AP OTS map with a Works filter. I did see hollywoodx verify some other filters on the HKS map. Maybe we could send him some logs and get his input.

that is your best bet

I will PM him and see what he says. I've been reading through the ATR help guide, and it looks like he will need us to do a MAF sensor calibration log. It says to log/view the data of 15 minutes of out of boost driving. My question is, if you log only the required PIDs (LTFT, STFT, MAF,RPM) would that allow enough space on the AP itself to log enough data? Or is laptop logging a must for that?

OP...you, me, and anyone else with a Works filter running an AP need to get these logs so we can try to work with Hollywoodx, Christian and Cobb and get some Works Filter OTS maps out there. It is afterall, the "most" powerful filter in existence. ;)

i dont think those drop in filter will keep your car so lean, hks,works k and n unless there is a big hole in those filter. plus if you use the stage 1 map, the afr pre set on that mods. the afr will not be that agressively lean as cobb will make it on the safe side.

run a stock filter with stage 1 and do a log look for knock retard, then do it again on works and hks. the diffrence will be so slight. not sure if you downloaded the logs if it still stays there on AP so it will not be full. you can call cobb.

I run the Perrin Drop in with Stage 1 Cobb with no issues. I monitored my Knock Retard, Injector Load and Boost during tip in and WOT and it was good. As far as AFR's, i dont think the Stage 1 + Filter will do any damage. It is all speculation with no AFR's though.
You will definitely see a difference in your Tune vs Stock.
Its fun...

According to Cobb, the HKS map works fine with a Works filter. That is the setup I have and called Cobb to confirm before installing.

Great info! Thanks

^^^^+1....thank you! works filter sounds nice, and i'm gonna keep it.

I've been running the 93 octane HKSPF stage 1 map from cobb with my works filter. No problems
