A shop in my area is a doing a full build (greddy tt, rods, pistons, sleeves, port polish, etc.) on a 350z and they are putting in a DTA standalone. The tuner says he can get the DBW to work with this unit. Anyone heard of it? What are you thoughts? Here is some info on it and the website. The model is the P8PRO. www.dtafast.co.uk

If you are going to go with a racing standalone engine management system, I would go with Magneti Marrelli. Some F1 cars use this.

A member on the board has made a harness for our car with this. I think there are two or three options, if you want to know more information about these units, i'll find the old PM and post it up. BTW, Injected Performance is using one of the two (or three) units available. ( https://my350z.com/forum/forced-induction/124849-injected-performance-350z-4-3l-spy-photos.html )

 

Whats the MSRP on this? Looks very similar in function to the Motec M800.

 

I don't have that info, but he quoted me $3,200 installed and tuned.

 

Holt ****! I thought I was crazy!

 

This really depends on the level of factory functionality that you wish to keep. I get the impression your installer does not really understand the full scope of the factory ECM and its complete integration to the rest of the factory systems. I can almost garentee that this system will knock a fair amount of your factory components out of commission. To include your dash and other parts.

The DTA systems are nice. We've tuned a few here but on straight SCCA race cars. They work well in that regard. I believe they are based on the GEMS board and software (the same company that makes AEM's EMS) although the screen shoots look much cleaner from an interface perspective.

I promise you that this is a very large job and $3200 seems quite low, but I'm not familiar with your installer. This type of system is going to come down to the installer. Honestly the risk is not worth it. There are two garenteed choices the Motec (if you wish to self tune the system) or the HKS F-Con PRO. Obviously I'm biased becasue we are an HKS F-CON PRO dealer but these are the pros. First is 100% proven. We've installed and tuned it on 12 cars. It functions and operates flawlessly. Start-up is so factory-like, you would never know its heavily modded. Cruise and idle are perfect. WOT is an thrill. Also its reasonably priced when compared to the Motec (over $6000 just for parts). The HKS F-CON is ~$4500 including ECU, Harness, WBo2, Sensors, Install, and Tuning. I cannot stress enough how hard installing a standalone system is in this car. Please call me and I will be more then happy to explain. Its much to much to transmit through writing.

 

same as any other standlone honestly...the trick to standalones is NOT the one you pick, but rather the person who tunes it.

 

He told me I would not lose any OEM functions, because the factory ECU will still control them inlcuding the DBW. I will definately wait to see this on the 350z project they have before I opt to take this route.

I was going to get the HKS, but decided against it for two reseans. 1. Limited tuners. 2. If I am paying $4,500 for it, I would expect not to lose any functions like VDC and cruise control. For that price they better get it right.

 

The MoTeC M600 is actually only around $4500 USD, including harness and etc.

I was under the impression that no HKS Pro-Dealers had fixed the cruise control, TCS/VDC, etc. feature problems that most lost (whether completely or not) when using the V-Pro.

 

both the megane trophy renaults
and the formula renault cars

use magneti marelli marvel 6r as engine management

the magane racecars uses a 330hp almost stock VQ35DE
the formula racecars use a 420hp heavily tweaked VQ35DE

 

If you get the Motec and all harnesses will it be plug and play like the UTEC?

 

I would have to check with Simon@Nizpro or Richie (300+RWHP N/A 350Z using the M600) to find out.

To give a guess, I don't imagine so.

 

Haha my fault. I read this thread

https://my350z.com/forum/showthread....ighlight=motec

but forgot it was in AUD not USD. Well I guess I can always tell Peter our currency is better engineered then his.

I have not kept up with the thread. Does the Motec retain all those functions (VDC/Cruise)?

 

No problem.

Yes, they had some problems with the DBW initially, but from what Richie has posted, all has been worked out.

His car is a daily driver, BTW. He is a real estate agent, so promptness is important (and i'm sure he has no problem with that kind of power).

 

Support use to be, what's the kind word, lacking, w/ DTA. Frank the US distrubtor, really didn't use to know his head from a hole in the ground. He use to be the only outlet for DTA here stateside. Things might have changed in the past few years but DTA USA use to be a part time 1 man operation.

As for pricing. The 3,500 quote is way too low. There is no way a competent shop is going to install a standalone w/ DBW and tune it for that price. If they believe they can do a quality job for the little money and retain all the standard features, it just goes to show how poor a grasp of the situation they have. To give you an example. There is no, I repeat no, standalone out one the market today that retains all of the OEM features. The gauge cluster must be run by the stock ecu, VDC in the the form Nissan designed is disabled, CC is gone.

Here is a bit of info on the Magnetti Marelli system. An SRA w/ wiring harness is going to be ~$5-6.5k. This will include DBW, CVCC, Traction contol, 8mb Data logging and a wiring harness built to IRL specs. You can choose to run the stock ecu as well to control the rest of the vehicles functions. The only features you will loose @ this point are VDC, & CC. The MM traction control system is pretty damn good so the vehicle will still be able to obtain straightline traction but loose the intigrated braking functions of VDC. MM will only allow this ecu to be sold and installed thru their authorized distributors. In otherwords, unless MM has confidence in you as an installer and tuner you can't even order the ECU. They care to protect their name and image as the best in the world that much.

If someone is interested in obtaining a MM ecu. Contact me. I have been working w/ MM since 2004 on the ecu specifically for the 350z's.
