Question for you: when you remove one of the OEM o2 sensors to run a wideband, can you run it that way long term or is it important to have both factory o2 sensors for the ecm?
Yep, BS. Crank HP -28% = rear wheel hp. Not a 350 lt1 na car will make 626 crank hp with a heads and cam. Never forget to do the math. But i will throw you liars a bone. The gen4 lt1 z28s are rear wheel hp dyno'ing 239 at thr rear wheels. Does that mean they all come from the factory with the corvette tune and mark down the quoted hp ?
PCmForless, damn I thought I had a decent tune from them on my 93 LT1 Formula Firehawk M6. I had done Mac mid length headers , 160 stat. She Dynojet dynoed 309 rwhp and 342 rwtq. Video is on my channel. From what you are saying there was some hp left on the table. That was 10 yrs ago and they came highly recommended. I will say the car ran very strong . Best run at Atlanta Dragway was 13.4 @ 103 mph. Beat a lot of LS1 cars back then.
He makes the comment about having 500-600 hp car and my @strongspeedworks tuned ls1 gto makes 300ish and I have an absolute blast beating it like a rented mule. But I do wish I had 100-150 more hp for the track
Regarding the LT1 timing, you said stock they're 33 and you bump them up to 35 or so, is that in addition to the 5 that PE adds? So the stock 33 will be 38 at WOT and your 35 will be 40? I just want to make sure I actually understand...
There is nothing in that tune that will add 5 degrees of timing in PE mode. There’s an unknown spark adder that is set to 5 degrees. I set it to zero. It has nothing to do with PE mode. I’ve never seen an LT1 add 5 degrees of timing in PE mode.
I have owned 2 1994 z28 6speeds, still own one now, and have changed 5 optisparks between the 2 starting in 2003 and they aren't that bad once you do it a couple of times.
Trying to confirm something you are mentioning: You are runing E65 and you are tuning WOT for an AFR of 11.5? I believe E65 has a Stoich of 11, so WOT on E65 should be tuned to about 8.60 AFR? or am I misunderstanding this?
There's kinda a debate on this. Most widebands read in lambda and convert it to AFR. So if it's at stoich in lambda it will display on the Guage stoich in AFR. So it doesn't matter what stoich is in afr, since it's converted by the wide band. Once again that's debatable and I've never seen any real info on it. I will say I've ran e85 in my camaro since 2009 and always tuned it by afr on my aem wideband and plugs read perfect.
This is freaking awesome. When I was a teenager I had Pontiac 77 sunbird with the iron Duke 4 cylinder, car was awesome. Great mpg. 15 bucks would fill it up.
@@strongspeedworks Nice. I got a brother in OKC. Buying a 94 Firehawk and I’m sure I’ll need tuning as I get her sorted. Loving the LT1 content. Thanks!
are those 17/15's? what size rear tires? fixing to pick up an 01 with the same cam specs and i don't like the wheels on the car presently but keep seeing different info on wheel fitment and i don't want a huge sidewall making the back end stick way up
Great advice good gears good transmission then and then a good motor runs in the right RPM ranges you have to get a loose stall I bet his car break in 8
Got my first lt1 f body yesterday needs some love but it runs and drives very good gotta fix the body up a little and we'll be jumping into the motor your video definitely helped me out on choosing how togo
My BBK alway stuck since 2011 when i got it but it wasnt TOO bad just FBO. Then when i did LE HCI and 24x (EFICONNECTIONS) Etc. It got REALLY bad while we where in middle of tuning my car. Thing started getting stuck at like 30-50% or so. Made me look like a real jackass that last day at the gas station 😂 that was the final straw. AS&M was thankfully on its way by then. It still doesnt settle down instantaneously like id prefer it too, but its so much better and it does zero out. I cannot recommend BBK tb for these engines unless just FBO and even at that point why bother until HCI or around 400WHP or so. Only reason why i had it at FBO was because i knew id go further with the car and its such an easy install. Unless you get it cheap used to test out id only reccomend a quality TB like the as&m unit. Also brandon FWIW with my BBK prior to it getting really bad every time it got stuck id just have to "blip" the throttle and it would settle down.
