Default ati timing situation

i bought a used kit from someone off the forum, i got it installed at MRC in spotswood, good install and everything. the guys were cool and reasonable and no what they are doing...... i like the kit and theres no problems so far. But its set at ati prefferences, so the kit is running rather sluggish, i raced a 2003 camaro z28 and he kicked my ***..... i was embarrassed, i thought i would win...... n e ways i want to get it tuned.... mrc does not tune otherwise i would go there, i think i found a good place to go to. im going to take the car to SPI, they do good work from what i hear, like supras and stuff, he told me to buy everything and they will install obviously. Alot of people with the ati blow up because of timing and what not, i mostliky am not gonna turn the boost up..... alot of poeple went with j&s safeguard to be safe, is there n e other computer or what not that i should no about, i would like to no other peoples setups, also is there a new j&s safegaurd out, where is the cheapest place to buy it from..... and im also thinkin about gettin a walbroro fuel pump and injector..... how much do they go for.. i no the fuel pumps cheap, but i seen injector for all different types of prices, one of the advertisers on the forum have pe injector for like under 200 i think.... does that come complete with everything. i already have a y pipe installed. i ordered a test pipe and a blow off valve, i like the sound....
thanx alot
thanx n e input is appreciated

the best way to go is getting a ECU reflash.... if you dont mind driving down to AAM in maryland they can tune the a/f perfect and set the timing maps..... I would ditch the fmu that comes with this kit, another solution would be get the greddy emange

You can pull timing via a ecu reflash or j&s safeguard. But if you're going to get bigger injectors you'll need something to control them anyways, I would suggest just get the ecu reflashed for the injectors and to retard the timing.

not sure if you have the money but before you get the ecu reflash I would really consider getting fuel return line with bigger injectors.... if you did go that route you can also go with a smaller pulley and have a very safe 400whp setup

ecu reflash if I recall is $599 but you would want the car on the dyno while they remap the ecu so I figure you would have to pay 2 hours dyno time also to fine tune it

I AGREE. I hate flashes cause they are not tuned for your vehicle just a generalized program so if you can have it done on the DYNO definately

If you are going with larger injectors, I would get the re-flash. I reccommend going with the 440cc injectors. I have seen them on the board going from $300-$400. You would need the Walbro fuel pump to drive the injectors. As far as timing is concerned, I would go with the J&S Safeguard. The Safeguard allows you to map your own timing and also protects against detonation. It is quite effective at retarding timing in case of detonation. The problem with setting your timing with the re-flash, is that you have no way of controlling it. You have no way to advance the timing if there is a little too much pulled. If you go with the flash only, you also lose any protection from detonation except the stock knock sensor and ECU program. The Safeguard recognizes the knock way before the ecu would. You can read more about it here: www.jandssafeguard.com. I am currently running it and I am very pleased with the results. The return fuel system is a good choice, but not absolutely necassary if you are staying below 400-410 WHP. If you plan on going beyond that, you will need it.

Bottom line, get the Safeguard at the minimum, along with a good tune before you blow something with an untuned ATI and not addressing timing.

I installed my Safeguard in one afternoon, not too hard, but not super easy either. If you have any other questions just ask.

this is true if he had to send out his ecu but since hes local and they would do the remap while his car is on the dyno there should be no worries.... if I were in the position where I had to send out the ecu for the reflash then I would rather just go with a fuel computer & the safeguard thats just my opinion though... I rather have everything controlled by the ecu if it possible

Another consideration is future mods. The ecu may have to be re-flashed if you decide to add other mods in the future, pullies, headers, intake, etc. That is why I reccommend the flash AND some kind of fuel/timing control. Emanage, Safeguard, etc.

I made the mistake of getting my ecu flashed too early in my modding, I thought I was going to stay where I was at, but now I am hooked, now it needs it again.

My friend had a bad experience @ SPI. He told them not to mess with his alarm, NOT to put his keys inside the car (because of the alarm) and some other small things but they did it regardless. They messed with the wiring of the alarm, locked his keys inside the car, and there were wire clippings everywhere. At the end of the day, he left with his alarm disabled causing some electrical problems. I was very shocked to hear this, especially from SPI.

After you flash your ecu, what is the cost to reflash from the additional mods?

I am not sure, but I think it is around $300. Somebody will chime in, I am sure.

Are you pulling timing from your flash or with the J&S?

As of right now, both. But I had gotten the flash first. I am installing new injectors and fuel system this week. I am then getting another flash with the stock timing maps. I will then be pulling exclusively with the J&S.

I've got a J & S Safeguard for sale as well as Walbro Fuel pump and brand new RC 440 Injectors

All are recommended for running the ATI

Check the for sale section

AAM's is $195. I drove my Z 4.5 hours to AAM to have it reflashed (worth it to have it done on the dyno). Made a little over 350hp @ ~7lbs.(would have made more but stock injectors didn't seem to want to take it on mine) and I put it through Tail of the Dragon the very next weekend w/no problems and none since as far as timing. I will say that I think the fuel return should be standard on anything F/I. Also, they're right about the injectors too. I locked one of my stock ones up on the dyno. Didn't sound good @ all! The problem with all that stuff is none of it's tied in together...the reflash set the timing according to rpm right? and the J&S sets it according to boost...they can't know what eachother are doing. Maybe the e-manage Ultimate will address alot of this in compacting everything into a simple system that more than 15 people in the US can tune .

I plan on purchasing a used kit myself, plan on doing the install at home with a couple of buddies. As for tuning, do the instructions tell you where to set the sliders for maybe a rich base tune? Im going to be real busy this next month and dont know when i will have time to get it dyno tuned, thats why i ask if there is a rich and safe way to run this kit. Of course during all this i dont plan to do any WOT runs.
