[RK Tunes ICS]

Hey guys, this is Jordan at RK Tunes.


A few may know me from Force Induction here on BF.c. I do a lot of tuning/flashing on the E36 chassis. Whether you have a supercharged car that needs a fix, built a new turbo kit, or have an N/A street car that just needs some more umph or functionality I have it covered.

do you have a dyno graph of a NA street car?

are you able to tune for:
M50 manifold
Dinan BBTB
Shorty Headers
Underdrive pulleys
24lb injectors
Porsche 803 3.5 in MAF

??

man this community is dying for a realistic standalone option, real time dyno tuning > pre-programmed chips all day.

I'll see if I can dig one up. In the mean time, there is no reason to use an 803 or 24# injectors for the mods you currently have. Those upgrades are only required on cars that are heavily modified.

[Redfogo]

yeah would love to see M50 manifold tune.

M50 manifold tune is available.

[ChuckDizzle]

what about turbocharged E30's? Looking for a retune with our setup

If your E30 has an M50 in it, it can be tuned.

[ChuckDizzle]

If your E30 has an M50 in it, it can be tuned.

Unfortunately its just an M20. But I'll keep in mind that you also do NA tuning now (I thought you only did turbo tuning), I'd like to get my S52 tuned by you down the road once its swapped in.

[Redfogo]

From a customer prospective the more dynos you have posted the better. Most of the venders seem to skimp out on how much there tune will improve. On common setups

[jjjjjjj]

I'd love to hear further explanation on this. It seems the 24# / 3.5 hfm combo is a popular mod.

In my case, I am building an obd1 s52 and plan on the following:

Obd1 S52
M50 manifold
S50 cams
24# injectors
3.5" 540i hfm
Full 3.5" intake with silicon elbow (no asc)
Pulleys
Riot racing BBTB
Long tube headers, single 2.5" or 3" exhaust(undecided)
93 octane

What kind of gains could one of your chips give over a similar TMS chip? Asking because I already have a used TMS chip that came with my swap engine but have heard nothing but good things about you and ICS from the FI folks. I'd like it as "aggressive" as possible for daily driving. I'd also love to see 250whp but not sure about that.

Feel free to PM me but I'm sure many others have a similar setup.

What is your opinion on this? Other tuners provide a NA tune with the 803 and 24 LB injectors and claim to provide extra hp and torque.
Not looking for or expecting like 50 hp but a better reaction out of the S52.

[Cyrix2k]

If your E30 has an M50 in it, it can be tuned.
I have a two part question.

A) Can you tune the 402 (non-vanos) DME? If so, how far will the stock MAF go in terms of power?
B) Do you have any non-vanos tunes for the 413 DME?

I have a non-vanos M50 swapped into my e30 right now and am looking to swap my turbo over with factory engine management. I'm just trying to see what's available for now - I won't have funds for a while.

The old MAF/Injector combo is a bit of a relic. Seems like it may have been a marketing ploy to upsell other parts. The only reason to change the MAF or injectors is if you run out of room using them. The larger MAF does not increase power, merely allows you to read more air if need be. The larger injectors are usually used on cars with cams/higher compression etc. The stock injectors should be fine to use with bolt on modifications.

I've heard that before. Seems like there's not substantial gains in moving to a 3.5" intake / MAF diameter?

I've read the arguments for and against the larger injectors/MAF. My question is: since my motor has almost 150k I'm going to replace the injectors with brand new units regardless of what size I ultimately choose. I had been planning for the 24lb Bosch injectors. What, if any, are the downsides of going to the bigger than stock injectors? Am I going to use more fuel, will there be bogging issues, is my air/fuel ratio going to be off? If there are no downsides with the 24lb units, that's what I'm going with along with 803 MAF, BBTB, M50 manifold, 3.5 CAI, elbow and ASC delete. I figure more air in cannot hurt but only help even if it just incrementally small. That along with headers and 3" exhaust will enlarge my air pump's (aka engine) breathing ability. That cannot hurt it seems.

So with all that said, can you tune for these modifications?

[propcar]

The thing is, do you really need to replace your injectors at all? If you're not using the maximum cycle of your stock injectors there's probably no benefit.

I'm rebuilding my injectors right now with fresh seals, filter etc. and I tested the resistance and it's all within spec.

[lunker325]

Interesting! Couple of questions.

How do you upload an OBDII tune with the $275 level?

How many revisions do you get at the $400 level?

I am guessing the cat delete turns off the rear O2 sensors, correct?

Exactly. It's not that it can't be tuned, it just isn't budget friendly to change out parts that aren't going to provide much of a benefit. All of the tuning can be dialed in for your exact setup if you provide us with some good data. Whether it be a dyno run, or some datalogging information. If scheduled appropriately, tuning can be done remotely live while you're on the dyno.

The ECU can either be shipped in, or a cable can be sent out. Does not include revisions at the $275 level.

At the $400 level, revisions will be sent til the car is setup properly. Does not cover modifications done down the road that would require further tuning, unless it's something like enabling/disabling sensors.

Cat delete does disable the rear oxygen sensors so your CEL does not illuminate.

not going to get into a huge arguement about it, but I've done dyno tuning on a track car with full bolt ons (obd2 s52) with stock cams, and the 21.5lb injectors definitely ran out.. Needed 24lb injectors, made more power, and created a safety buffer.. Dyno proven, and required

Jordan, do you have an answer for this?

I figure at 150k the original injectors are probably close to being worn out. So, yes I am going to replace them. I could rebuild but it's just not that much more to buy new. And I see very little price difference (if any) between 21.5lb vs 24lb units. So why not go with the 24lb ones?

If you put quality fuel in and change filters, Bosch injectors go for a very, very, very long time. Easily over 200k miles.

This is interesting because, for the s50 with #17 injectors, it seems to be common knowledge here that the engine will run lean up top with those mods. Any thoughts Jordan?

The S50 may have issues, the S52 with it's slightly larger injectors do not require modification as often as advertised by others.

[dsomma325]

Jordan does great work, guys. He tuned my brother's S52 with Schrick cams and made nice gains over the chip he was previously running...

[200kclub]

Thank you for the response. Right now I'm building an s50 car that will have High flow mid-pipes and TMS headers with a cold air intake and 3.5 maf. I would really like to tune for all these mods with 24# injectors to avoid those problems. How buisy are you these days around Philadelphia?

[99MPower]

:drink1

you would be wrong as well....

[emtres]

what kind of gains would one see with generic bolt ons like intake/exhaust/m50 on an S52?

[Redfogo]

^^I would like to see a graph of this as well.

[RK Tunes ICS]

Will get some more appropriate N/A dyno graphs up here soon.

[lunker325]

Good deal. I would like to see a stock vs tune dyno with AFR's.

[Hurleyboarder21]

Bump I think a lot of people are waiting to see those graphs! I know I'm one of them!

[Marv17]

I sent you a pm. Hope to hear from you soon. Going to be buying a tune soon so need to make a decision on who can provide the best customer service along with their product.


One thing I did forget to mention in the pm is that are you able to turn off the evap code? I get p0455, large evap leak, but my car is a 318ti with a S52 so the sensor/wiring isn't the same and the ecu can't get the correct signal. Wanted to turn it off all together.

LMK soon!

Thanks.
