Black bear tune help..

[TogaPC]

This thread is awesome thanks for the feed back but I have some noobish questions what is the MAF and PCV even thought I have tons of post the lingo is still new to me I have only been in and around my car since December. Thanks guys.

PCV is Positive Crankcase Ventilation Link and MAF is Mass Air Flow sensor Link.

The PCV valve is an often overlooked maintenance part. Both the MAF and PCV valve should be checked and cleaned or replaced if necessary at least once a year.

Also, I would never run anything less than 93 octane if you have a 93 octane tune unless it was unavoidable. That being said I have to run 91 when I go home to see my folks but I generally run some octane booster to compensate. If you only have 91 octane than have Justin send you a new file for 91 octane. Your not going to see any benefit from getting a 93 octane tune and running 91 octane fuel.

If i add performance parts after the tune will it bog down they possible hp/tq i could be getting with a retune? im going to TRY to add as much as possible before the tune bc idk when the next time justin will be in NJ lol

If you add performance parts after your tune it will not "bog" it down, but it will mean that your tune is no longer optimized for your specific set up. Think of it this way, If he gets your AFR (air fuel ratio) perfect with your current set up, then that is your engine making its maximum potential HP for those modifications, So then you go and add a intake, and exhaust and this changes the amount and rate that the vehicle can breath in air and let exhaust out then the tune will no longer be perfect and it would be best to get a re-tune.

What are some lower budget performance enhancing things I can do to this rig every item under 450...Ik AEM polished brute force is on my list..what else!?

I got my K&N intake for around $300 from the auto parts store (O'Reilly's). It would be best to do all these mods before you get the tune, and if you cant get it done in time for Justin to tune it in person, you could always get on the live cable tune list when you have finished modding (or when youre close to done that way you would get the cable about the time youre done).

im planning im doing some stuff before i get the tune im looking at the AEM Brute force i found it for $230+ shipping i would go k&n but i dont want a oil filter and its xheaper and better looking as far as im concerned it preforms just as well =D what about E-Fans?

whats everyones thought on BB's autocal.....i dont have the money for it now and have already put down 50 dollars for the Nj meet but i think in the long run itd be better to have so you can tune and update tunes as you mod...

While its not as detrimental on an NA motor vs forced induction, its probably not the best way to go about driving. The ecu only knows to pull timing ONCE it's detected knock. It has no way to know you've put in 87 instead of 93 and will try to give it all the timing its tuned for. It will knock, and then pull timing. I think the GM ecu will keep the long term compensations in, but Im not positive.

Knock is bad for any motor, and can lead to premature bearing failure. You may not think its that bad, but if the motor knocks at 150K instead of 225 or 250, do you really KNOW if it was the added bearnig wear from the knock?

Better to run the fuel its tuned for.

I agree that ANY knock is bad knock. I was under the impression that the PCM blends the high octane and low octane timing tables. Its called adaptive spark. Did anyone mention the coolant bypass mod and a lower thermostat?

I just got the autocal about a month or so ago. And have nothing but praise and good things to say about it! This had made tuning so much easier, granted you have to data log, but once I received my tunes from Justin (who by the way, is absolutely the man to deal with) it was only a matter of a couple mins start to finish to flash them onto my ECU. actual flashing process takes only about 45sec at best. Funny thing is, after doing my post tune data log for Justin, it came back as my truck running slightly lean. Come to find out, I have a fuel pump on the way out (in the shop as we speak). So this thing has limitless benefits. As well as the code reading function.

One thing about Black Bear also, their customer support is exceptional. Turn around times have been extremely fast, emails back and forth (especially with me asking a million questions) have been quickly responded to. Nothing but A+++ to say about them.

ill be bying it maybe next summer its half the price if your and existing customer =D

Looking forward for this meet! Bought myself Corsa exhaust, headers, and e-fans in anticipation. Gunna order some plugs now, see you there!

You will love all 3 of those items!!

See you there as well(if we are the same day)!! I'm forth on the list lol I wish I had time and $$ for an exhaust I want Borla or slp but times running out! Buying my brute force Cai today and vette servo!

Ah, I am back at 14th, so probably wont. Your gunna love that CAI, gives your truck a mean sound. I've also heard great things about the Vette servos too, got mine ready to go in whenever I get my exhaust and get my truck on a lift..

 

[sparg93]

I'm going to the NJ tune as well - see you guys there!!

 

[01HDtahoeNJN]

word! idk if you guys checked but someone mentioned getting a meet together since we alone have 30 ppl...i need to do plugs wires and throttle boddy asap =/!

last question where in the pvc & throttle body on our nbs's?

Yes, that was me.

I threw the idea out, but i haven't gotten much of a response for interest. I'd be happy to set the whole thing up, I was just hoping to see some interest b4 I went through the motions.
