DINANTRONICS X In-line Performance Tuners for the Toyota GR Supra

[Syeeee]

Can these be used safely with a dp, catted or catless?

I don't see why not.

Yeah, DPT X would function fine with a DP. Would not correct for the resulting CEL in the case of a catless setup, nor would the DINANTRONICS take advatange of a high-flow or catless setup (aka add more boost since there is less restriction), but it would physically perform largely the same regardless. May be some minor performance gain by virtue of the better flow from the DP's but that is about it.

If I'm understanding this right, is the difference between the factory downpipe and any aftermarket downpipe minimal with this product? What about AT vs MT? I thought the most common way to go with these cars was an aftermarket downpipe with some tune. Also, the dyno numbers posted were on a 100% stock car?

Thanks!

Can we finally order in California?

Sort of. It uses RC hardware (internal board and harness) but uses a unique calibration to Dinan. And a different enclosure obviously. That said, its plugging into the same sensors so the variability between callibrations is nuanced at best. Pulling the same levers after all. The main difference comes in terms of throttle tip in and how that is mapped. Dinan focuses on a roll in so power is as smooth as possible rather then the abrupt hit of torque down low that is seemingly common. Gives you the feel of power but ultimately it results in sacrificing a bit of the top end.

As a side note -- we have developed our own piggyback hardware in the past that was incredibly advanced for what it was with individual injector drivers and everything else along with a harness that plugged direct into the ECU. Problem with it was it was expensive and at the end of the day still couldn't offer the features that a true flash tune would. Given the price it had to sell at (the harness alone was nearly $500 a unit at our cost) it just wasn't sustainable given market adoption. A simple sensor based piggyback could do the lions share of what it did and the drop off in drivability for most was unrecognizable so we went the sensor route. Given quantities of scale it just made more sense to use a proven hardware component that was cost effective going forward so that was what was done.



The different map settings ultimately just incorporate higher boost being applied -- at least as far as this conversation is concerned. Each map is ~0.4 PSI more than the one before it. Depending on quality of gas the demand may be more then what can be handled effectively and the engine will pull timing, stutter, etc. We designated those maps to octane based on what we see in the field as to where those limits are. Map 6-7 should run flawless on any 93 octane or higher. Map 1-3 is really for 91 and then Map 4-5 are the hybrid maps for folks like Canadians that have Petro 94 which is more like a upper end 91 in US terms. Horrible California summer blend 91 would be map 1-3 whereas Winter blend is actually better and could likely run map 4-5 without issue. At the end of the day not all octanes (even with the same rating) are the same so we tried to make that clear for where folks may run into drivability issues.



CARB ETA is always a mystery wrapped in an enigma. Your guess is honestly as good as mine. We've had applications take 3 months all the way up to 3 years to get run through the the gauntlet and get approved. Hell, some of the BMW intakes given carbon traps that CARB has no testing procedure for have been in limbo for close to a decade.

No dyno's on map 5. 93 is the primary octane here in AL and what the vast majority have access to so we just report the best case. That said, map 5 is roughly a pound of boost less than map 7 which would equate to ~15 WHP down at peak.

any member discounts?

Has this been tested on a MT with catted downpipe? JB4 has issues with tuning on MT

Correct. The inline tuner is callibrated with the OEM downpipe in mind so does not take advantage of a downpipe with lesser restriction that could then take more heat being introduced into the system.

There is not.

Has been tested on MT vehicles without issue. Has never been tested with a DP (catted or catless) as its not a configuration we support. Our product line is geared to be 100% legal, emissions included.

Thank you

I don't suppose there's an update on CARB approval?

I wouldn't have confidence in running it on MT with a DP since they react poorly without EWG control(like JB4) to compensate for reduced backpressure.

May I know what is the difference between part number 0166 and 0168?
0166 is for 2-port supra, while 0168 is for 6-port?

Thanks!

@Dinan_Engineering my Dinan cat back, intake and inlet pipe will arrive this week, and I hadn’t planned on doing a piggyback or tune until I decide where the weak parts of the car are (6 months of ownership so far, 2024 MT).

I also got the CanCheck MFD so I can see as well as hear what the car is doing before I make any choices about performance uogrades

I just learned about your piggyback, and might add it while I have the intake apart.

Two questions:
1. Did you do any in house map testing with your full bolt ons?
(I assume negligible difference from stock if so, but curious if you optimized anything as a complete package)

2. Do you have plans to add maps in the future, based especially on the recent release of the Final Edition Supra which shows very different hp/torque numbers?
