Maf or mafless...the more i read the tougher it is...

[trbojo]

So, i talked to Eric a few days ago and was set to go with a ls1 maf, translator, powerlogger and wideband chip....then i start reading more on here about how a speed density chip is better if you have an overboost condition it automatically compensates...but then i've read that mafless chips are a pain in the ass to tune with....sometimes too many choices makes it difficult to make the right choice.....any input?

If you've got an overboost situation, you've got to get a handle on that and correct it. Trying to tune around a problem only causes more problems.

the reason i am using a MAF is because new cars still use them - my thought is if MAFless is better the new cars would be MAFless.
Tuning - i don't have a clue.
Good luck which ever way you go.

Speed density works well on a track car but a maf is hard to beat for everyday drive ability.

I like all of Eric's chips. The basic one will take you a long way. The 6.2 has nice features that you do not have to use if you're not ready for experimenting. The SD is a bad mofo and unless you change injectors will have all the features one could ask for in a chip. If you are an instruction reader you will have minor tuning to get it right. If you throw instructions to the side and jump right in the car, you will hate life until you decide to read the instructions. I would do the 5.7 for anything. The 6.2 is a good buy for the ones who want to tinker and learn more about tuning their own.

I have the TT 6 chip (not SD), it uses the MAF for part throttle like normal, and then at WOT it uses A/F tracking to try to hit a desired A/F ratio. Eric can set it up to be close to your goal if you set the boost to be what you told him. It requires the powerlogger upgrade though. But you can then log everything like boost, KR and wideband A/F. This has been the easiest way for me. MAF requires no tune to tweak for drivability, then at WOT, the A/F target is handled by the computer. I can run 18 psi boost, or 30+ psi boost (once accidentally) and all I do is change the base fueling in the powerlogger interface, leaving A/F targets alone.

basically what i was looking for..so wot only-mafless.....daily driver-maf.....i don't have an overboost condition...like i said, if one were to happen, i read that sd auto compensates. i.g.-the wg hose pops off.....looks like i'll go ls1 maf....now.....screen or no screen???

I had mafless, converted back to maf, it's the way to go for simplicity. Keep the screen in.

It depends on the chip how much intake air can be measured. Extender and Extender extremes have a extended maf range that will continue read air flow past 255. Other chips hit 255 and stop reading.

A Bob Bailey Extender chip with a ls1 maf and a basic translator are hard to beat.

Just my $.02

And the Gen II translator with the extender chip has wideband tracking option as well.

I still think its all based on how fast you wanna go. Limited87 went high 9's with a stock ECM and factory MAF( more then once)...thats good enough for me.
I tend to look at it this way...why make life more difficult when the factory parts will get you that far. A factory ECM and a Powerlogger are pretty cheap and very reliable.
