idk.

i just relized i put one extra zero on those miles also

it was like 1,200

I put my money on a bad tank of gas. Seeing that your car was driven so little, I doubt you were draining out all the old gas and filling it in with a fresh tank of gas everytime you drive the car again (say after sitting for a month).

I've seen way too many motors blow up because of that. The longer the fuel sits, the shittier it becomes. Guys just leave their cars sitting for 1-2 months, and one night they just take it out and rape it. Bye bye motor.

 

This entire discussion regarding street tune is so misinforming that I don't even know where to start.

Obviously, there are just as many guys who blow up engines on the dyno. This is all based on who does the tuning, and how competent the tuner is.

I have seriously walked into tuner shops and seeing these tuners trying to tune a fu*cked up car. Messed up wiring, leaky injectors, and engines that were misfiring. A good tuner should know how to spot problems, have a facility to repair all these problems, and also know the potential problems that may arise. We don't just sit there, play with some fuel maps and try to nail A/F's and go absolutely **** with a few deg of ignition timing.

I am a guy who swears by street tuning. The moment my cars leave the dyno, the tune doesn't even match the real world conditions at all. I always finish off with final street tuning, especially when we can replicate launches, aggressive downshifts, hitting the rev limiter a few times, etc... stuff you can never do on a dyno. I have a 5km straight road near me and I finish off some street tuning early in the morning. I would record a few logs, do some adjustments, and make sure everything is perfect.

The last I remember reading about this, it is not even a liner deterioration. Depending on temperature, you may lose one or two octane numbers in a month, but once the fuel starts breaking down chemically, the octane #s start dropping rapidly.

This is true. About 90% of cars that come into our shop 'only needing a tune' actually end up leaving with an invoice that includes quite a few hours of diagnostics and repair.

I would be embarrased to bring a car in that shape. Hell, I was pissed because I blew off a charge pipe and had a slight coolant leak due to lose worm gear clamp the first time I got my setup on the dyno.

BTW, car was never street tuned but drives/idles like stock. Could be the combo of EMS and Mustang dyno though.

..i hear that ****. On a 600-700hp car making 4th and 5th gear high boost pulls on the parkway gets a little hairy . just ask Miller lol.

 

of the 50+ cars I tuned last year, 3 were on a dyno. As long as you don't get greddy with the timing map, know how to look at a plug and realize the shortcomings of the ems you are using (aka hondata with lack of IAT correction) then lower power cars will be fine.

most cars I get are just stock block cars with 50 trim turbos running 8psi of boost, they don't need fine tuning to pull out that extra 10whp, they need to be able to handle shitty gas and the temperature differences that range 70+ degrees here in KY.

as for my personal car, I try to street tune it, but when we turn on the nitrous and the tires spin in 5th...well I pretty much datalog at the track and correct, or dyno. Big hp cars just can't get traction on the street.

i wasnt tryin to kill you...

 

People need to post up some crazy street tuning experiences. I've had two people run from the cops while i'm tuning and have had numerous other dangerous encounters with it lol. It really helps when people know how to drive high power cars though. I.e. both hands on the wheel

 

Never had anyone run, but I did have someone tell me he would run if the cops chased us.

I have ONLY been pulled over ONCE in about 150+ street tunes (knock on wood) and that was for a loud exhaust of all things. Kid was military though so the cop let him go

Everyone always tries to race us in the middle of a tune however...only once did it happen right at the end when we could really put the tune to the test

I only have stories of the cars nearly falling apart, the checklist on my website is derived from people's car's i've seen or been in. My favorite line item is "passenger seat must be fully bolted in with 4 bolts." I had one car i was tuning and doing a 3/4th gear pull, can't remember, but thought he saw a cop, so slammed on the brakes. My seatbelt was fine, but i found out the back two bolts were not in the seat, damn laptop almost fell out of my lap. Regardless to say, car didn't get any more pulls that day, as we went back home.

I have had a few people try to race us though, but normally i'm just in the part trottle stage and haven't even tested any of the boost areas.

On one of my big hp cars (h22a+gt35+spray) I've had some interesting looks, as it has a side exit exhaust in the front bumper.

 

We had one customer who failed to tell us he had a leaking wheel cylinder, so we nearly had a brake failure. And then there was some stupid lady walking on the dirt shoulder and not the sidewalk on the other side of the road we use to tune, so we probably passed within 3 feet of her at around 115mph. Other than that, it's been pretty uneventful here. I just seem to be a magnet for people who have $2500+ for a turbo kit and tuning, but lack the $5 for a new wheel stud.

I prefer to do the initial tune on real world loads that the vehicle will only ever see on the street. Then go over the timing and possible cam gear adjustments on the dyno.

The following pictures are the map from a customer's car that I was unavailable to tune, so he went to another "reputable" tuner. His engine melted all four 9.5:1 84mm bore CP pistons on the way home from the dyno session.

low cam fuel


low cam timing


VTEC fuel


VTEC timing


Notice how uneven the maps are. There was not enough load on the engine to cause audible detonation, so this tuner didn't retard the timing in boost properly. Also the fuel values were way off. Once he hit the freeway, I would assume it was 13:1 to 13.5:1 in boost based on comparisons with my original tune for his car.</TD></TR></TABLE>
those ignition maps are worthless, timing stay the same, he never did retard the timing whatsoever, timing stay the same as 0 vac column, and there's no way you could tell the mixtures from the fuel maps, anyway, those ignition maps are what killed his motor

I can sure see there is a lean spot in column 10... I have tuned this car several times. I can look at the map and estimate weather it was rich or lean. Remember I also can see the duty cycle, and compare it to his old map. I know it was lean. Excessive timing and lean conditions killed it. It was more than timing alone. I do have his dyno chart that shows it went to 12.5:1 in areas while it was on the dyno. When it hit the street I know it went leaner under the increased load.

yea i've hardly seen any get actually pulled over lol. Once was for exhaust, tint, cracked windshield, etc and another time one guy actually did get pulled for speeding.

The two times I had people run was in busy areas of town which was scary . One guy didn't have a license apparantely and got all sketched out when a cop came to see if we needed help while we were fixing a charge pipe coupler on the highway. I guess after seeing him act sketchy and running his plates, which turned out to be from his old civic and not from his current integra, the cop followed us into town. We got off at a gas station and the cop just left. When we pulled out 5 minutes later he was on our *** again out of nowhere. So the guy pulled into the 7eleven and the cop went and parked across the street where he met up with 2 other cops. At this point the guy i was tuning was freaking out. He tried making me drive and I said hell no . Finally he pulled out and the cops all got on his tail. He all of a sudden decided to mash the gas and run away through an office building area during rush hour. All the cops turned on their lights and started chasing and we actually got away. Although because they had ran his plates he was found by them at his house the next day and ended up going to jail for a few months lol.

The 2nd time we had just gotten back from the dyno with my friend's car and were heading back to his dealership to pull off the tuning equipment. He decides to test out 1st and 2nd gear on a main road where cops are prevalent and sure enough we hear sirens and see blue lights coming up from a distance. Who knows if the cops were chasing us or not, but he freaked due to not wanting to lose his dealership job and all and jutted into a nearby appartment area. He was going pretty fast and hitting speed bumps at full speed(about 4 of them). I was like watch out for the speed bump and he said " i dont care right now". The car was practically going airborn on the bumps . He ended up with a slightly dented header, but was able to evade the police and get home without getting caught.

I've had some pretty crazy stuff happen to me while tuning

 

This is why street tunes are dangerous...idiot customers

 

Street tuned a 300whp KA-T, can't say I'd do that with any more power, dyno time.

 

Honestly...if anyone ever ran with me in the car, id upload a bogus program into the Ostrich to slow him down.

Im not dying for the price I get for a street tune...

 

Damn, you guys have it the hard way. No way I would allow a customer to drive the car while I am doing the tuning. Plus the customer will never know when to take it easy or let off the gas if something wasn't right with the engine. How do you guys tune the car with the customer behind the wheel?

Usually if I needed to be on the laptop during a tune, it's always nice to have a brother who will do the driving for me

I don't. The owner of the shop I tune at does all of the driving. He has been building motors long enough and is proficient enough behind the wheel that I feel comfortable.

How does he keep from getting tickets? I know i wouldn't risk getting tickets driving customers cars on the street.

I dunno about you, but tunning my LSvtec on the street scared the liven **** out of me.

Made almost 370whp @ 10.5psi, and we street tuned it at 20psi

lets dyno the bsuxteen, k?

(after the street tune of course )
