Just flashed it going from v5.3 to 5.8 (5.7 gave me burble issues).
Car pulls like a train. Tried to get logs but beat up roads ruined them. Definitely felt more linear and powerful up top. Cheers Halim.

I have the XDI 35 pump and on 5.7 I was getting pump noise at startup does this fix that issue? I have selected the pump option everytime and still getting noise even with my custom tunes. It has been a nightmare |

I don't drive in the top end range much anyway to really tell a difference. I drive in my city mostly and do short accelerations from 2nd to 3rd when there is room in front of me from other traffic. On top of that, it seemed like there was more top end when I did my 4th gear pulls yesterday. However, Halim says I wasn't running the v5.8 tune when I thought I was. So... I don't know and have no way of really knowing haha. |

Just got back from flashing Stg 2 5.8 E30 and was doing some logs, but the logs crashed and didn’t record.
Overall, upper RPM is much better, but it doesn’t pull as hard as my Stg 2H 5.7 E30 map. I was watching the dashboard and MAF was hitting 42-43, whereas 5.7 2H was 43-44. Didn’t see any knocks or major timing pull, even had IATs up to 135F (hot day here). Gonna see if I can get a Stg 2H E30 5.8 map to smoke some guys at the track next week, but I def recommend trying 5.8–nice upper RPMs! Last edited by ZM2; 09-04-2019 at 02:12 PM.. |

It would be nice to know whether 5.8 gives up any torque in the lower rpm ranges....to get something more in the upper rpm ranges. That would not be a good thing..for my needs. I try to keep all shifting on the N55 below 6500...as a general rule anyway. Not sure how that could be easily verified / quantified tho....and I definitely don’t trust my seat-of-the-pants.

The higher the number the more power you're making. You can use it as an indication of HP at the crank, roughly 10hp per lb/min is the rule of thumb. Judging by your logs you could use the pure inlet, my car only makes 14psi due to altitude but I'm hitting 40-41lbs/min on Stage 2 91. I'm not sure what the range is on the stock MAF, I've seen pure turbo logs not making many more lbs/min, it might cap at a certain number because it can't read beyond that range.

And yea, inlet pipe is on my list. But was gonna do inlet, dv+, xdi-35, wmi, and ps2 all at once after winter. Didn't think the oem inlet was a restriction on stock turbo. EDIT. Nvm, I'm thinking of the MAP sensor, not the MAF. |

I was told by tuners on my other car (2007 saab 93 aero) that 1-2 per log is okay. Doing some real quick googling, it seems that it depends on what caused the knock. Going WOT or letting of the gas or shifting gears could cause knock and it be okay. It would be a false flag. I looked at my logs real quick and do not see "normal" behavior like that that could cause knocks. So it's back to the question of if 1-2 knocks are okay. |

Regarding knock, I stopped running the 93 tune because no matter how much boostane used I saw it regularly on my logs around 6k, which was a bit worrisome. Never figured out if its phantom or not since the timing rarely corrected for it and the car felt perfect. |

Hey guys, here are a ton of pulls on Stg 2 E30 5.8.
http://www.bootmod3.net/log?id=5d72ee45c090c6192c630438 http://www.bootmod3.net/log?id=5d72ee46c090c6192c63043a The upper RPMs feel much better than my Stg 2H E30 5.7 map, and timing is rock solid even as IATs get high. Boost target and power is down slightly, as this is an OTS Stg 2 map, so I'm going to try to get a Stg 2H E30 5.8 map to see how it performs. Here are the details on my car: Dinan turbo, Wagner Evo II Comp IC, HJS 300-cell DP, FTP pipes, CSF & do88 coolers, E28 fuel. Again, I definitely recommend giving Stg 2 5.8 a shot b/c of how smooth it is up top. Lastly, I'll reiterate how wild it is that MAF only drops from 43 to 42 as IATs go from 90F to 145F. Gotta love ethanol... Last edited by ZM2; 09-12-2019 at 03:48 AM.. |
