What's better Lap3 or Power Chip? I'm thinking about chipping my Stinger GT soon.

If you’re talking about actual ECU tunes I don’t believe lap3 has released theirs yet. Also I’ve never heard of “power chip” and nothing about them comes up on a Google search. They’re either only in Canada or possibly just a generic copy of the JB4 chip.

Most people would say to avoid unproven brands and use the top selling and highest performing chip like the JB4.

There is one reason why ecu tunes are better. You can disable ecu errors and removes catalyst completely (remove all subroutines related to them). None of the boxes (jb, lap) can't do this (lap3pro says they can, but i dont know how). And without removing catalyst and decreasing backpressure it's like playing with fire.

From my point of view the best is Ecu tune + cat delete and full stage 2 tune and jb4 on top + water meth injection. Thats how i am going to tune clients car in couple of weeks (waiting dor jb4l). We got with st2 + 100 hp on top of stock car ans hoping to get another 100 with jb4 + meth.

I thought the jb4 can be used to get rid of check engine light when running catless.

i believe if u r in another country then usa u have the option too.

Removing the check engine code yes. A ECU tune will eliminate the code from ever occurring through programming changes.

Jb4 dont think so. Lap3pro can shut down check engine light. But its not about check light. When we are tuning stinger ecu, we are removing all catalyst related subroutines (heating and etc), you cannot disable this just by shutting down ecu error. As fsr as i understand, those boxes just clearing this error when it pops up. Correct me if I am wrong.

I’m pretty sure some people with jb4 and fully catless had there jb4 to send a dummy signal to stop a check engine light from happening.

You are correct, but only for non-US customers. There's some kind of regulatory issues in the US that made BMS eliminate that option for US customers.

I don’t believe a word of any shop saying they could remove the flash counter. I haven’t found verifiable proof of a single one that could do so.

If anything, it would be better to go the spare ECU route and swap back to the original for dealer visits.

Like others have stated, the dealership wouldn’t be the ones to do the digging. It’ll be a request from corporate before extensive repairs are authorized and once they see the flash counter in connection with the times, that likely won’t match service records all bets are off. I wouldn’t go down that path.

I had a Cobb tune on my Bmw and flashed it back to stock for warranty work all the time. I’m sure there are other tuners who can do the same so I don’t know what you’re saying ??

Tunes can be reverted back to stock, that's not an issue. Where you can run into problems is if the dealer suspects a tune caused the warranty repair, they can scan the ECU and most modern ECUs leave a count for reflashes. If they determine there are more flashes than the OEM put against it, they can suspect a tune. Supposedly some tuners claimed this can be "ghosted" but there are arguments against that.

A respectable tuner will not reprogram your ECU up to the limits of your car's components, let alone beyond. Therefore, it is unlikely, although remotely possible, that you might break something after tuning. That is why I chose @PRESSERtech LLC. They have an outstanding reputation built upon tuning high performance imports and exotics that exceed what the majority of Stinger owners can afford to purchase. I figure, with these people trusting them with expensive autos, I can too.

There is a huge difference between using a piggyback to trick your ECU through manipulated sensor signals and having a competent tuner reprogram your ECU. Thus, reprogramming the car to run without cats and O2 sensors is better than blocking a signal or faking signal to avoid a code that should be there. Like most things in life, you get what you pay for. My preference is to have the best and I recognize that comes with a higher price than something that is less than the best.

A shop like PresserTech can also help you modify your car to any level while customizing a program that optimizes how all components work together to produce your best performance with acceptable risk. I do not worry about whether or not Kia can see how many flashes my ECU has incurred because I've chosen the path of maximum reward with highly mitigated risk.

Well stated.

M8, to flash stinger ecu you need to fisicaly open it. It means goodbye warranty.

And it's nothing to do with a tuner (skilled or not), kia can fall apart even without a tune. On my stinger on 11k miles died high pressure fuel pump (1k usd to change), what else will die, nobody knows, on one of the guys stingers 2.0 engine died. On a stock car, no tune.

Also I've done a lot of dyno tests and with moderate specs Lap3 / jb4 / ecu tune make +/- same horse power. The only difference with the first 2, you don't have to open ecu's. I am not talking dual gtx3076 turbos on a Stinger, I am talking about basic bolt ons such as intake / exhaust, intercooler.

And if you want a dragster, get a dragster.

Hp between piggies and tune are the same but tunes are faster due to more power and faster throttle opening during LC, faster shifting, and holding power over a broader rpm range.
Very soon ecu programmimg via the ecu connector / pins so no more ECU crack open will be needed.

Please stop spreading nonsense. Opening the ECU does not void a warranty. It doesn't even void the warranty on the ECU, let alone the powertrain.

As with any modification to the vehicle, the manufacturer must prove the modification caused a failure. This isn't my opinion, it is the law. Read the law and get additional clarification for whatever you don't comprehend while reading it. Then, study the case law to see how the law was interpreted by the courts.

Would love more info about this..

 

[Tonkabob]

Would love more info about this..

Lets do this with pictures....
Log shows fast throttle open, no throttle close on the 1 ,2 shift, flat afr, high and sustained boost with less taper, timing with all cylinders in sync, less timing drop on shifts.

The Gs in the dragy show the strong no snip launch and fast shifts.

Can't see as much in a 1/4 but low ET and high traps showing it all works.

M8, it does. Believe me. If something serious goes wrong about your car, coreans can request online video of your car. If something is wrong with your engine and gearbox, the first place they will check is ecu. Thats why we stoped opening up ecu's. I talked to several dealers and it's 100% warranty loss.

Also I tested back to back stingers with flashed ecu / lap3pro (i have their original software for lap top, so I can tune those boxes) and with 2.0 we get the same numbers. But with lap3 I do 3 maps for client. Stock (95 octane and 2 maps for 100 octane). Because the limitation is not a tune, but the turbo.

The only difference with lap / ecu flash is the throttle tuning. Yes, with lap we are not touching it, with ecu flash we make it sharper. But on the other hand, you can floor the throttle to get same result.
