Let’s see what can of worms this opens up…. I find myself with a newly modified turbocharger which gives mush increased flow, and therefore in need of engine management to keep from over leaning the engine on boost. At least that’s my take on it. I don’t have MAF yet, but have the usual bolt ons… 3” car less exhaust, Tial dual port, MBC. 15 lbs boost. Fully rebuilt engine. Street car for occasional DEs.

looking for a bolt on engine management system, or a way to reliably manage air/fuel, ideally while eliminating air flow restrictions. Emphasis on bolt on and reliable. I do not have any shops for local support, and tuning is foreign to me. Cost is also important. I’ll add this too… in the event that I decide to sell the car, I don’t want the system to be a deterrent to the sale. Meaning not something abnormal that the buyer can’t find anyone to help with.

What system would you go with?

There's not a ton of stuff available for this platform. You can go full ECU change but you mention cost. I'd suggest contacting John @ Vitesse Racing to see what he can offer you.

thanks for the response. I’ve been in touch with John. His MAF is my most likely direction right now. Just want to explore the options before committing. It’s a large investment.

I agree with Patrick's advice. John will provide what you want and support it. Surely support is the biggest challenge with other solutions.

15 psi isn't a lot of boost. Chips and a 3 bar sensor should cover that, some chips have settings to run larger injectors also.

If you are ok with retaining the stock AFM the Rouge A-Tune is the way to go. Yes you will still have a restriction but this is 100% PnP and will most likely meet your requirements of low cost and provide support for 15 psi of boost. I run at approximately 15 psi boost with a stock rebuilt K26/8 and its pretty nice.

Thanks Mike! I went to check it out. Not sure A-Tune is still available new though. Link at Lindsey Racing site is dead

Rogue's A-tune was always stable for me and a good way to go IMO, but yes Joshua is gone and I don't think Lindsey is selling them anymore. Support is key and with Joshua not in the game anymore I'm not sure I'd go that route.

Vitesse has an AFM option that also uses a MAP sensor feedback. Vitesse also has the MAF option that uses MAP sensor feedback. John/Vitesse provides awesome support and has been around for a long time. I cannot recall ever seeing any negative feedback on Vitesse products.

You are really doing yourself a disservice to continue using an AFM in any capacity in 2022 when MAFs have been tried and true for 20+ years.
Night and day difference in responsiveness and engine breathing.

You wont need any support with the Rouge. It's 100% bullet proof. Plus I passed SMOG in SoCal with it.

I've only read the website with Vitesse prices, and I'm not knocking his products or his services, but way too much money for me. If I were to go stand alone I'd definitely go with a speed density as that is really a bullet proof non restrictive reliable way for engine management.

I really like the AugTronic ECU. Stock air filter box (which will be a bottleneck for high power) and the AFM replaced by a MAP sensor. Fully programmable and several options available (if you have enough cash).
A new version of this ECU is in the making.

I had a lot of time for Joshua but he's off the scene and there seems to be very little support for the Rogue brand. Plus we saw a lot of people experiencing issues with this product. Yes, Vitesse isn't super cheap but John has been around for ages and his service is legendary. I would prefer to pay extra for something that is proven to work and has great support than the opposite.

Mike Goebel

The Rouge A-Tune cost $300!! You simply can't beat that!! It all depends on what you want to do. I worked for an EFI manufacture and the cheapest kit we had with all the harness/sensor usually came out to about $13K +. I do not have one of those kits either .

Maybe the A-Tune is not enough for your requirements. Who knows???

Thanks

Does the Atune adjust fuel flow to the correct level for a car with a custom built turbo?

Mike Goebel

Will the stock injections be retained? They will only deliver enough fuel for about 300 crank HP at 3BAR fuel Press. That will be your limiting item. Which turbo mod? Raptor from evergreen? K26, K27? To be honest it’s kind of difficult to say it will work with a mildly modified turbo setup. I think there is a guy on here that is using the A Tune with a Raptor setup. I think his Rennlist name is Saecay.
