Going MAF less, it's not just for your race car anymore.

[BLACK6PACK]

C&C,
That is what has me baffled and upset. I was expecting to be close to 120 with my mods, but the best I have been is high 114. O2s are right at 770, egt 1640*, 25-26 lbs of boost with dual nozzle alky setup running 100% denatured.

My biggest problem is tires. Right now I'm running 275 50 nittos, which are only about 25.75" tall. I am going through the traps at around 53-5400 rpms. I'm also only pulling 2.0 60's. I either light up the tires off the line or about 40' out. I need some 28" slicks.

That is what I needed to know.

I hadn't planned on running race gas and alky. Since I have the ME and 2 timing setups, I need to have it set up so that I can use both timing modes. Right now I am using the race settings with 93 and alky, so when I do run strait race gas, all I have for adjustment is boost, other than the million and one things the ME lets you adjust.

I guess I should play around with it some more, to see what I can get out of it, and how it reacts to different input before I send it back for timing changes. Maybe it will run better on 93, alky, lower timing (19*)and major boost (30psi), than it did with higher timing (23*) and 25 lbs of boost.

There is alot to running WI or in your case AI.
Contrary to what so many people want to believe, there is some tricks to it.

Like you want to run 25-33% of fuel volume for max effect.
WHERE you add it changes it from being best used for atomization, or vaporization.

Then it also effects the chemistry of the actual reaction.

Weird. 1640* is almost bang on where my car was at when I ran 11.55 @ 177 as well as 11.38 @ 117. I was also running 24psi and 27* timing. I have stock heads and cam though so technically your 25psi should be flowing quite a bit more air than my 24psi was.

Nitto's are not going to get the job done for you at your power level. You need real slicks. Dunno if true 28" slicks would be too tall for your cam though? Maybe some 28x9's (actually 27.3") would fit the bill for you? Dunno, just guessing as I have no experience with alky nor do I have to deal with the heat that you have in Florida. I ran my 11.38 on a good air day which put me at or possibly -100 feet below sea level.

I guess I need to run strait c116 sometime at the track, and see what kind of times I get. I haven't ran it with this combo and pure race gas. It'll be a good test to see how much I'm loosing with alky.

You could be burning in the exhaust driving the egt up and 1 wire 02 down.
Lean it out, watch for KR. If the egt drops, opposite of what you think would happen as you lean out, then you were overrich by a bunch.
Steve

 

[BLACK6PACK]

I read that when you posted it before Steve Y. I thought it was weird until I thought about it. I don't think I was over rich. I kept leaning it out. It started out around 820s on setting C. I dropped it down to setting B and then dropped it down a pound at the rail on the last two runs. Each time the 02s dropped and the EGT went up. I can tell when it gets real rich on this car. It noses over pretty quick. I left the track and turned the boost down about 3 lbs and hit it, and it felt pretty weak. I have a very accurate and sensitive butt-o-meter.

very interesting thread. I have a 3" IMP with the Trans + but considering the mafless ME. programming for air variations is an issue but probably not a big deal at near sea level.

anyone interested in a trans + and some 50 injectors???

another ??? does anyone use the new "truck" MAF used on the Z06 vette??? it flows pretty well if you want to stick with a MAF.

I may experiment with using both the Trans + and the ME. I can see that for going 9's, a Z06 MAF with the ME & Trans + might be OK, but the "too many gizmos" thought keeps coming to mind. parts left out don't break.

how can I get on the mafless bandwagon.

any idea when this setup will go prime time??? I drive my car on the street but have other vehicles to allow for tinkering with the turboslut.

Hey folks, just got back from vacation....

Steve Y, thanks for lookin out for me....

As bruce mentioned. The MAF Translator and late-model MAFs function as a drop-in replacement for the stock MAF. The Max E has been used very successfully with this setup. The Translator Plus adds timing adjustment that is not chip dependent. The timing adjustment works with the Max E as well as the stock chip...

The Extender chips add top-end fuel control to a translator or plus equipped vehicle. The Extenders have many other useful features as well.

Now...... would there be a need for a "timing tuner" device? If so, what features should it have? How should it connect? What do you guys think?

Let me know!

Bob

Don't know when the Max E-R will go "prime time" but I think that at first he's going to make them available to previous Max E 16 users who are already familiar with the Max E tuning.

Give Steve an email at maxfrt1@usol.com He will probably want these units primarily on the "faster" cars that will be able to take advantage of the no maf, and in the hands of experienced Max E tuners.

Again, to note, for the average 12 sec "or quicker" TR/GN, who just needs to replace his bad maf, the Chevy maf with a trans or trans + makes a great upgrade.

hope this helps,

not that mine is "fast" ;^) I just got to play with the driveability stuff <g>

All sunburnt, and ready to go back to work? <g>

Would this be something that would be stand alone, and work with basically any chip? And would it just take out timing, or swing both ways? Could a two step for consistant launch rpm be added in it as an option for the bracket guys?

Sounds interesting........

Thanks,

Dwight

 

[TurboBob]

The timing would be adjustable both ways.

It would work with ANY chip

My plan was a "splice in" connection under the dash. Put the unit in the glove-box.

It's very hard to 2-step the Buick coil-pak although I'm working on some other stuff...

tan, not burnt.

I've been in contact with Steve as he's been putting the final touches on it. With these additional tweaks, mine is working even better now than a week or two ago, and I was perfectly satisied then. The around town and highway driveability and response is better than anything I've used before. The various tuning capabilities are a really great feature to fine tune your particular combo.

I would say if your are interested in going "mafless", he can probably fix you up now. Again, I don't think this is necessary for a 12 to 13 sec daily driver, and it is for an experienced tuner. Admittedly many guys have gone and are going very fast with a maf. There's more than one way to go fast, and they all have their merits. I am just happy that there is now a mafless alternative without having to go to a FAST/Felpro/DFI- system.

As far as customer support goes, Steve Yaklin is tops. You wont find better.

$$ ?

I'm currently running a T+ and would be interested in going MAFless. It seems like the timing adjustments would be really cool. Is a price set?

 

[elevensecgn]

Give Steve an email at maxfrt1@usol.com and he can give you more info as well as cost. I would also give him the total rundown on your combo. Injs, turbo, cam, heads "yada yada"

You'll also need to get ahold of TurboBob to get your ECM mod done for the MAP input and his harness for same. And you'll need a 3 bar map.

The timing tuner device that TurboBob is working on would compliment the Max E R well. I guess since you already have the T+ it will do pretty much the same thing but will just have some functions that are not used. (MAF translation)

TurboBob, any more info on the timing tuner yet??

Spark Translator

The project has been given the green light.

I have the details worked out. Just have to get some prototypes together.

Everyone interested, let Ramchargers know. They will be the warehouse for them.

Thanks guys!

Bob

As soon as it is ready I'll post it in new products.

I can't keep up, I get the 16 POS ME & now this! My car is still broke down & I want this upgrade anyways!! Great work Steve!!!

 

[lazaris]

I've been testing the Max Eff no MAF for quite some time. At this point I have to say the driveabilty is the same if not better than with the MAF. Throttle response is crisp and idle quality with 83 lb inj's is excellent. Kinda tough to get 83's to idle nice but it does and with no MAF to boot!! On my car Im looking for a nice gain with a straight 4" inlet to the turbo. I'll post my results on a back to back test with it as soon as possible.
