| Well i would be very careful on the throttle until you can get the Gen V on because 4* in 1st is pretty bad. I cant really say the best way to solve the KR in this case, but the safest thing would be to pull the timing so that the PCM doesnt have to work so hard to keep the pistons in tact. Otherwise you could try to pour some fuel in there to cool it down but its still iffy. I would be very cautious until the new blower goes on. _________________  1996 Riviera, 1.9s, 3" DP, FWI, 180, AL104s, 3.6", DHP PowrTuning... Soon: SSACs, Stage 1 TB, and a 3.4 |

| Your LTFT's look like you're still running lean, since they should be 0 at WOT (and ideally all the time). On your first scan your O2s were in the 700s, way lower than than the 900s they should be in. Were you running E85? _________________ 1996 Riviera, 1.9s, 3" DP, FWI, 180, AL104s, 3.6", DHP PowrTuning... Soon: SSACs, Stage 1 TB, and a 3.4 |

|  your O2's are way too low at ~700. i dont know much about tuning, but i would try adding in a lot more fuel, but i doubt that would help much. You are close to maxing out your maf, so i assume you are going lq4 with the gen V? next time you scan try getting a longer run in. the point isnt to just go wot from a stop. roll into the throttle and scan to at least 100mph (provided its a safe road). mark at least these parameters: KR,rpm,O2,LTFT,mph,mafhz &TP% _________________ 3.4, N*, 1.84RR, P&P blower and LIM, 3"DP, 4"WAI, plog, 6K HID, Eibach pro springs, KYB GR-2, Fbody 12" brakes,caddy STB & sway bar.

| No need to scan ign volts, but thottle % would be nice. Your scans will be higher res with fewer parameters scanned. STFT is sometimes needed, but probably not here. Boost can probably go away. I agree, I've never seen 700 O2 values, and if I did I would be concerned. Is there E85 in the mix? Maybe could explain. Also LTFT should lock at 0 at WOT. Why are we not seeing as much KR in the 2nd scan? Did you change something? It's too bad there is no O2 here to look at. _________________  |

No i was not using E85... I will do another scan tonight after work... with O2 one from 10-100mph

| Please post your full mod list. Please scan for IPW in addition to what you already have. (it's in your first scan) Please scan for MAP instead of "boost". Please scan for TP% Try to scan in 3rd gear or 2nd to 3rd. There is not enough load in 1st gear to make it count. Your timing fluctuates quite a bit in that 2nd scan. I would like to see tp%. _________________ '98 Buick Riviera; Gen V 3.25 pulley, N*, VS Cam, 180 stat, Custom PCM (Powrtuner), headers & HF cat , 42.5 lb inj.

| O2s look better than before but ideally should be in the 900s (meaning you're still running lean) This can also be seen because your LTFTs are still above 0.

Those are your mods? Nothing else???? (injectors maybe? list everything please) 1.9s are not enough support to run a pulley that small. Sorry bud, not gonna happen, unless you know a tuning god. I tried for a long time to run a 3.2 pulley with the same (plus 42.5 injectors) and never got it to work. Too much heat from the S/C. You can dump all the fuel you want (I showed 10.5 A/F on the dyno at one point) and it doesn't get any better. Your scans look just like mine from my 3.2 pulley (only you have more KR).
Your only options are:
more fuel
less timing
but I don't think it's going to help much._________________ '98 Buick Riviera; Gen V 3.25 pulley, N*, VS Cam, 180 stat, Custom PCM (Powrtuner), headers & HF cat , 42.5 lb inj. Grant-built/PRJ/Thrasher trans 3.29 gears, 7/8 chain, zzp hardened IS |

Start with DHP 1.5 and scan. Then tune. Then scan. Then tune, etc., etc. |
alright.. i have the DHP 1.5 on and the LQ4 tables in... ill post me real questions later after phucking with it a lil more.. thanks guys_________________ 1.9RR's, SSAC, LQ4 maf and N*, Gen V-ported, L32 LIM ported and polished, L26 block, L67 heads, tune, E85, 65# injectors Worthy quotes: | Rickw wrote: | | What a dipshit, grow up. |
