Im wondering If alchol injection can be contolled with SAFCII. I plan on having an ecutek flash on my ecu.. fine tuned with SAFCII..im wondering if alchol injection is added on top of that would the SAFCII controller be suffecient to realize gains safely?

 

yes it will... Many use safc for this including myself.

 

To be honest with you if you get an Ecutek flash custom done on a dyno theres really no need for an SAFC. Secondly, im sure it can tune for the alcohol but it can't do anything the stock ecu can't so keep that inmind when tuning with it. Also be mindfull of the properties of the alcohol 6:1 is usually an optimum mixture as I think Al uses.

 

Ah, so you use alky, too. That's not the same as just saying "93 oct." It's about equivalent to running race gas...

 

Interesting, i was pondering about this setup aswell. You guys must have pegged the safc -50 lol.

 

-50 lol seriously. Well I would really like Al or someone to comment on if the setup is possible or not..for one thing, all the highest pulling stock turbo cars i have seen are all using safcII.. so i plan on keeping that in the mix somewhere. This is just a random thought. Maybe its possible to have the car tuned to run on alochol... yet have an SAFCII map that would add fuel in the event something were to happen to the alchol unit. This would give you time to run the car safely untill you had time to get home and check out the system... The other way to do it would be to have the car flashed with out the use of it.. then have an alchol map. I have ready some of Als posts however and hes is saying that he runs his alcohol maps at 11.1.. however he adds timing advance. It sounded like it was beyond the possabilities of safcII.

and as far as mixing. If I decided to do it I would want to use something consitant like washer fluid as the injection substance... perfect mix everytime. I wouldnt be seeking enourmous gains, but hte price of one of these kits is $500.. that is less then any of the intercoolers and actually gives you a dramatic jump in performance. For my needs..being able to add 20whp and run the car cooler/safer would be worth it to me.

 

bdking, did you get your car running right yet?

I would do that first before you start pondering all this other mumbo jumbo.

 

yep car is running right. 10 minutes with paul at EIP and easily diagnosed the issue.. the timing had skipped a tooth which is holding the hp back. The car is getting all new kevlar belts, cams,test pipe, injectors etc on the 30th.. my car still made more torque then any of the stock internal cars( and half of the cammed cars) at the gruppe-s dyno day in 105+ degree san jose heat... so i guess if you mean running right as in better then average, id say that would be a yes. Its also been to two autox and performed great since he fixed the problems.

Im hoping the next step will be an alchol map for 300+

 

Where you at the dyno day? Or are you comparing a totally different dyno at a different place on a different day?

What hp/tq numbers?

I could play that game too, I dynoed 13whp and 28wtq lower at the dyno day than I did a month before on the same dyno. Did you know it was over 110 degrees at the dyno?

 

Key to getting alky inj working smoothly with SAFC do the "MAP mod", and not run it in TPS mode.

TPS tuning with alky doesn't work well, as you need load based reference to remove fuel with load as alky is activited at a certain boost pressure.....basically RPM vs Load fuel table, which is what you get with the MAP mod on the AFC.

 

Absolutely farthest from the truth. It can vary a LOT. 30%-50% or more. Mixing yourself 100% distilled water and 100% alcohol is the perfect way to mix.

Definately possible while running a/f's safe enough to have a meth failure and not blow your motor. You NEED TO HAVE A WIDEBAND however to keep tabs on the health of the system.

Racegate is one of the nations best meth tuners. Al is not the know all for Evo's and has relatively recently started using meth and selling kits (6-8 months). Racegate has 3 years or more of experience.

 

Washer fluid is also a bad idea because it contains some material which can clog nozzles. I have seen this first hand in other people that use it. I would stick with pure alcohol, and mix it yourself if you like to mix things. I will say, I have played around with alky, water, and a mix of the two, and have always had the best performance with 100% alky. I have no product, nothing to sell, I'm just offering my input based on what I learned to try to help. I'm sure Al is just as capable, but I mean Scott (above posted) has SAFC and alky working...in real life, not in theory...what more do you need? It works.

 

Mustang dyno at EIP.. stock MR posted 209 there a couple days earlier.. that dyno reads lower if anything then the gruppe-s dyno but maybe a few whp or so but pretty much = .. When my car was having problems it was at 200whp.. posted 186 at eip on the dyno in question when it first got there and it was on one of the hottest days of the year on my 10th or so pull. 222.5/242.3 with jacked up timing at 11.3. I any event you constant shots at my car are invalid.. maybe your timing belt skipped a tooth too and thats why your car is weak now(bitterness?) besides you even stated yourself that you richened your cars tune? so WTF? ... if your going to play that game you might as well not even compare dynos from different hours because im sure the amount of available oxgen was steadily decreasing as the day progressed.


Back on topic.. I asked my tuner about this and they attempted a SAFCII tune with alcohol with bad results ( not sure if they try the map mode). Ill wait to see what others have to say..

 

Bad results? The results are very good when configured in MAP mode.

 

yeah.. bad results as in the blow something up lol.. not saying it cant be done with good gains... hmm so when you run in MAP mode, what kind of effect does this have when off boost? Im just trying to determine the draw back of MAP mode.. why wouldnt one used it when no tuning with alochol?. just trying to figure out the drawbacks.
