Extremely Lean After Enthalpy ECU Install - Page 2 - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

How did he verify the knock sensor was out? I have had problems with the knock sensor on my car in the past.

I had a lean problem with enthalpy as well. I triple tested all my components and even tried it with two good used nissan oem mafs. Nothing did it for me, I had to give up. But Martin is the best at customer service, he tried all he could (including sending me different tunes) and was always there to answer questions and even trouble shoot by the phone. I would have love to have been able to have it dynotune by him, to the point that im still considering making the trip to have him dyno tune my nistune. Anybody knows if he does that?

IIRC he can

Yeah, sometimes tuners post the itinerary for states or counties they'll be in and will try to schedule you in if you're lucky.

Some will even fly out of state to do a tuning session. Money talks!
So if you're not real close to martin, talk to your local shop with access to a dyno and see if they are willing to do a dyno day, see if Martin schedule is open and see if he'll do the dyno on a scheduled date. There might be specifics that Martin might request, like wiring complete, no leaks or no coil pack cover and a list of relevant mods and maybe even the ecu and tuning software you use. You don't really want him there to fix your car either, so be courteous.

Just try communicating with him!

he does dyno sessions in houston / dallas at least 4 times a year.

from the last houston day a couple weeks ago...

I told him it was throwing a knock sensor code... Check your codes, Knock Sensor was the only one I had and thats what was causing my issues...

Thats awesome man, nice S13, btw, love the tiffany blue

Do you have an engine bay shot, would love to see your set up

Does Enthalpy dyno tune your car for free when you get their mail order ROM tune?

That's weird that you guys are experiencing such issues with your knock sensors..I've had knock sensor code 34 on my ka-t for years now and my car still ran great. I never really looked into it because the code only popped up with my JWT ecu which was actually an OBD 1 95 ecu. Whenever I'd swap the stock '97 OBD 2 ecu in the code wouldn't pop up.

Enthalpy on tunes S13 ECU's and then uses a jumper harness to go from S13 to S14 ECU, thats what the difference may be...

Not free prob 100-150 for a dyno re tune plus dyno time.

This. To be quite honest (he will tell you also), most of his tunes are spot on and he does very little tweaking on the dyno. If you have a basic bolt on setup, you might see 5-10hp difference if he does adjust anything. In my case, I had aftermarket cams where we were initially at 20psi and 380whp, tweaked the tune, made 382whp at 15psi.

Martin knows his shit and if you ever meet him in person you can tell right off the bat. Like others said his customer service is top notch. After his dyno day ended in Dallas, he drove 3.5 hrs and met my buddy and I at a shop in Houston at midnight to load tunes on our cars just so we could drive up to the dyno the following morning. He will go out of his way to please his customers. There has been multiple occasions i have seen him do things that I know for a fact most tuners wouldn't do just because he cares and is trying to grow his business while helping out the community.

Interested in how he did that. I always heard you need a 500 to 1Kohm resistor on the cable that goes to the ECU, so he probably soldered that in the ECU. But i never did it on a nissan engine.

Tried it on a toyota ecu but it didn't work ( the work differently, it is a pain)

I'm not completely ruling out the possibility that Nissan designed the stock ecu's with two fuel/timing maps, but I just have a hard time believing that they wouldn't have mentioned it in the FSM. Case in fact: My engine was producing devastating knock on boost which ended up cracking ring lands on #4 and there was no apparent change in the driveability. Even JimWolf himself told me that the knock sensor is there to retard timing under light loads and was mostly used to "protect" (although very minimal) the engine from bad gas, etc.

I am not confusing anything. Until the feature pack 1, a nistune was just modifying OEM data stored in an eprom in the ECU. The FP1 actually modifies the code and removes the knock maps to make some room for the flexfuel system.

The FSM is a manual for stores, not for reverse engineering enthusiasts, that is why the info is not in.

I believe nistune makes a demo version of its software, it is very crippled and unusable to tune, but you can test the UI on it and see for yourself. You can also check the address files, they are provided in the "rom pack" . You will see there is a knock fuel map and a knock timing map. If it sill is not enough, i think i have the code somewhere for a ca18det (lower level is different from sr20 but it works the same way. It is also easier to understand as it actually was written in asm on the first versions, not compiled as it is on the 44F ECUs). It is a 6802 MCU, which is a very old and simple µcontroler, so it has very few instructions.

Seriously don't do that. It is the nastiest piece of crap you can fit on a MAF system.

I don't understand why so many people want one. That thing changes the MAF signal, and your ECU relies on this to set fuel AND timing .

Tuning the K and latency values is a 30mn work, and it does not requires a dyno, just a wideband AFR sensor.

KAT-PWR · 05-15-2015, 11:58 AM

My first experience on the dyno with Martin. Spent the prior night going top feed, installing cams, new turbo and downpipe; had a stripped fuel rail bolt that was sort of holding. Went to dyno fuel rail kept backing out boost leaking. Paid Martin, he said hey man i got you on the next tune.
Next time i was ready. I think i started around 373 then made 38X Martin asked what i thought. We both knew 400 was where the car should be. One more pull, boom 400.

I've literally been dealing with Martin 4 years. I have always been very satisfied with his performance and service. No complaints except that i don't live in Tampa closer to him.

Are you still trying to convince him there are indeed knock maps for timing and fuel? Forget about it! It's harder to relearn people than a Nissan ecu! That goes for "fine tuning" with a safc as well!

Tuning the k and latency is easy, but that's not where the power comes from. I can confirm that an un-tuned Sr can make 350hp from a 2871r @ 17psi with just a mafs and an injector upgrade. Still people are like, this tuner tuned my blah blah and I make 350hp at 20psi.

And yes I've tweaked a few of enthalpy tunes, they are usually conservative from my experience and can benefit from dyno time if you want more power. Not everyone needs more power or to conserve gas though, so if you just need your engine to run correctly you're good to go!
